Optionally, there is the enabled option in the [main] section defaulting to True. Packages listed in installonlypkgs are never automatically removed by this command. It removes the specified packages from the system along with any packages depending on the packages being removed. It also removes any dependencies that are no longer needed. There are also a few specific autoremove commands autoremove-n , autoremove-na and autoremove-nevra that allow the specification of an exact argument in the NEVRA name-epoch:version-release.
This command by default does not force a sync of expired metadata. See also Metadata Synchronization. Non-interactively checks if updates of the specified packages are available. DNF exit code will be when there are updates available and a list of the updates will be printed, 0 if not and 1 if an error occurs.
If --changelogs option is specified, also changelog delta of packages about to be updated is printed. Please note that having a specific newer version available for an installed package and reported by check-update does not imply that subsequent dnf upgrade will install it.
The difference is that dnf upgrade has restrictions like package dependencies being satisfied to take into account. Performs cleanup of temporary files kept for repositories. This includes any such data left behind from disabled or removed repositories as well as for different distribution release versions.
As necessary upgrades, downgrades or keeps selected installed packages to match the latest version available from any enabled repository. If no package is given, all installed packages are considered. See also Configuration Files Replacement Policy. Groups are virtual collections of packages. The default history action is listing information about given transactions in a table.
When no transaction is specified, list all known transactions. The replay will perform the exact same operations on the packages as in the original transaction and will return with an error if case of any differences in installed packages or their versions.
The transaction can later be replayed by the History Replay Command. Warning: The stored transaction format is considered unstable and may change at any time. It will work if the same version of dnf is used to store and replay or between versions as long as it stays the same. Default is transaction. This command by default does not force a sync of expired metadata, except for the redo, rollback, and undo subcommands. The info command limits the displayed packages the same way as the list command.
Makes sure that the given packages and their dependencies are installed on the system. See Install Examples. If a given package or provide cannot be and is not already installed, the exit code will be non-zero. The former version of the package will be removed in the case of non-installonly package. This behaviour is specific to the install command.
Note that this can lead to seemingly unexpected results if a package has multiple versions and some older version is being obsoleted. It creates a split in the upgrade-path and both ways are considered correct, the resulting package is picked simply by lexicographical order.
There are also a few specific install commands install-n , install-na and install-nevra that allow the specification of an exact argument in the NEVRA format. The list command also limits the displayed packages according to specific criteria, e. The exclude option in the configuration file can influence the result, but if the - -disableexcludes command line option is used, it ensures that all installed packages will be listed.
Modularity overview is available at man page dnf. Install module profiles, including their packages. In case no profile was provided, all default profiles get installed. Module streams get enabled accordingly.
This command cannot be used for switching module streams. Use the dnf module switch-to command for that.
Switch to or enable a module stream, change versions of installed packages to versions provided by the new stream, and remove packages from the old stream that are no longer available.
It also updates installed profiles if they are available for the new stream. When a profile was provided, it installs that profile and does not update any already installed profiles. This command can be used as a stronger version of the dnf module enable command, which not only enables modules, but also does a distrosync to all modular packages in the enabled modules.
You can add these folders at the top, or parent, level or as sub-folders. Sub-folders can also be added to other sub-folders.
Personal folders appear below the system folder list, after the Trash folder. Sub-folders that are added to system folders appear below their parent in the system folders list. The new folder appears under the systems folders list or as a sub-folder of a parent folder, depending on which option you choose. When you look at a mail folder, the contents are displayed in date order from most recent to oldest. To sort messages within a folder by different criteria:.
You can perform a case-insensitive search for characters or words that appear in the following areas of the message:. Note: We recommend that you do not use the entire message search as your primary search type. Depending on how many messages there are in the selected folder, a message search can take a long time, and your Webmail session could time out before the search completes.
To clear the search results, click the X in the corner of the search field. Webmail allows you to use filters to sort and order incoming mail. Mail can be identified using a combination of criteria and conditions to trigger one of three actions:.
The Contacts tab is where you add, group, manage and delete contact information. Contacts supports drag-and-drop so you can quickly move contacts to groups.
You can also address messages to one or more contacts from within the Contacts pane. The Contacts tab is divided into three panes: groups, contacts list, and contact details.
You can add contacts from the Contacts tab or directly from your email. Once the contact is created, you can display the contact and then click the Groups tab to assign the contact to one or more groups. Toggle on the groups where you want to add this contact. The basic search located at the top of the contact list uses display name, email, first name, last name and all fields.
If you want to do an advanced search,. Groups are an excellent way to create a list of commonly emailed contacts for quick access and easy addressing. The Groups list displays alphabetically, and contacts can be added to multiple groups at once. You can add contacts to a group by displaying the contact, and then selecting the group to which you want to assign the contact, or you can select one or more contacts and drag the contacts to the group.
Webmail allows you to import a list of contacts from another mail application that is in vCard or CSV format. The Calendar component allows you to create and view calendars. The Calendar component includes:. An event is anything that you want to schedule on your calendar, for example, a meeting or an appointment. Note: It is possible to add more than one event in the same time slot.
The RSS section allows you to view content from your favorite blogs or websites. Instead of going to each website to look for new content, your favorite sites are listed in the RSS section. When you click on one of the feeds in the list, you see a description of the items on that site. The items are ordered from newest to oldest, and the list is updated regularly.
Each item includes a link to a web page where you can read the complete article. Categories allow you to group feeds and make it easier to locate the ones you want to view. Note: When you create a new category, it is not displayed in the list pane until at least one feed has been added to it.
By default, categories and the feeds within each category are listed alphabetically, but you can change their position. You can create up to folders, including sub-folders, with up to files in any one folder. Note: File and folder names can be any length, but if the name is longer than 80 characters, the name is truncated in the File Sharing display, and the missing part of the name is replaced by ellipses Before you can upload a file, you first have to save the file to your computer, and then you can upload it to the Files section.
You can create up to folders, including subfolders. Subfolders can contain other subfolders as well, and you can nest subfolders up to 5 subfolders deep. All folders are displayed in alphabetical order. When you upload files to the Files section, you can specify the folders where you want to store them. If you have already uploaded files, you can move the files into any of your existing folders. Note: When you delete a folder, you also delete all of the files and subfolders that are in that folder.
If you delete a file that is shared, anyone who was viewing the file will no longer be able to see it. Files and folders will always display in alphanumerical order.
If you receive a file in an email and you want to save it to the File sharing, you first need to save it to your computer. You can then upload the attachment back into your Webmail Files. You cannot attach a file that is in Files to an email message; however, you can email the URL for the file. To share a file or folder, you must first mark it as shared. Then you can let people know about your file or folder by posting its URL via email, website, blog, twitter, etc. The file names still appear in the list, and you can rename or delete them, but no one will be able to view or download the files until sufficient time has passed.
The Settings component allows you to configure general settings for each of the mailbox components for example, display, and language preferences , mail settings setup, autoresponders, signature, allow and block lists, and forwarding options , and spam settings.
Allows you to manage mailbox folders. You can select the folders that you want to be displayed, and you can create, rename or delete personal not system folders. This section allows you to create and save text that you can use when replying to messages. This section allows you to add another email account to be displayed in the Webmail inbox.
The section allows you to change the password for your account and set up additional security like two-factor authentication and app-specific passwords if it's enabled. This section allows you to create a message that will be sent in reply to all incoming email messages during a specific interval, such as when you are on vacation. When enabled, incoming messages will be forwarded to the recipients that you list in this section.
Allows you to set up a backup phone number and email address to recover your password via email or SMS. This section allows you to define how incoming mail is handled automatically. This section provides all the information needed to sync your email, contacts or calendar to an external client, like Mac Mail, Outlook, or Thunderbird.
To enable a vacation or out-of-office alert, you need to set up an autoresponder message. A filter is a set of conditions that you define to handle incoming email automatically.
You can set filters to sort incoming email to various folders, delete unwanted messages, or forward messages to other email accounts. The action you prepare is triggered when the rules you create are found to be true. Webmail can analyze the following fields in the message header: Subject, From, To, size, and a wildcard that you can define. The fields can be evaluated according to the following conditions: Does or does not contain, is or is not equal to, does or does not exist and does or does not match expression.
You define the value of the condition. Plus sign tagging allows you to identify and filter incoming email according to a tag that you add to your email address when you give your email address to an individual, a group, or a business. You can set up filtering rules that recognize incoming mail that is sent to the tagged address and move it to a specific folder. By using the plus tagging feature, you will also know whether your email address has been sold to a third party.
If you start receiving unwanted or spam email that is addressed to your plus sign tagged email address, you will know that your email address was sold, and you can easily create a filtering rule that deletes any future email that is sent to that tagged address.
The allowed and blocked senders lists let you create a list of senders that will either be automatically allowed and bypass your spam filter or be automatically blocked from being received into your inbox. Addresses that are in your Contacts are considered to be in your allowed senders list even though the contact entries are not displayed in the allowed senders list. If you add an address to the blocked senders list that is also in your Contacts, the address will be blocked as the blocked senders list takes precedence over your Contacts.
You can add up to 1, entries each in the allowed and blocked list. The Admin component allows domain administrators to administer email accounts.
They can perform common administrative tasks for email, such as resetting passwords, creating, deleting, and modifying users. Note: The tasks in this section are only available to domain administrators. From the drop-down list, choose the type of account: Mailbox , Forward , or Filter. Names can be up to 64 alphanumeric characters including underscore, period, and hyphen symbols. The first character must be alphanumeric. Diacritics and special characters are not allowed, underscores or hyphens cannot be used as the first character, periods cannot be used as the first or last character, and two consecutive periods cannot be used.
From the drop-down list, choose the workgroup to which the new mailbox account will belong. Enter the alternative names for this mailbox. Messages that are sent to an alias are delivered as if they were sent to the actual mailbox. As you can see, this cmdlet has a lot of parameters, allowing it to address a wide variety of scenarios. Because your Windows PowerShell session can be long running, there may be times when you want to remove a module.
You do this with the Remove-Module cmdlet. A typical user rarely needs to remove a module. The Windows PowerShell team almost cut this feature because it turns out to be quite hard to do in a sensible way.
When a module is removed, all the modules it loaded as nested modules are also removed from the global module table. This happens even if the module was explicitly loaded at the global level. This organization is shown here. This is the master table that has references to all the modules that have been loaded explicitly or implicitly by another module. Any time a module is loaded, this table is updated. An entry is also made in the environment of the caller. In the following image, Module1 and Module3 are loaded from the global module environment, so there are references from the top-level module table.
Module1 loads Module2, causing a reference to be added the global module table and the private module table for Module1. Module2 loads Module3 as a nested module.
Because Module1 has already been loaded from the global environment, no new entry is added to the global module table, but a private reference is added to the module table for Module2. The updated arrangement of modules is shown here. The final arrangement of modules is shown here. This is done by creating a file with the '.
For example ' ftp. A way to fix this is to specify the exact version of the two packages that you want to install. To do this, first determine the full version numbers of the affected packages.
An easy way to do so is with 'apt-cache show' :. For each of the above you will be given a list of versions. The ones in the MariaDB repositories will have "mariadb" in the version strings and are the ones you want. With the version numbers in hand you will be able to install MariaDB by explicitly specifying the version numbers like so:. Even after having installed these specific packages versions, running ' apt-get dist-upgrade ' will still try to upgrade the packages to the highest version available.
After MariaDB is installed, and as long as the version number issue exists, an ' apt-get dist-upgrade ' will try to remove MariaDB in order to install the "upgraded" libmysqlclient and mysql-common packages. To prevent this from happening you can hold them so that apt doesn't try to upgrade them.
To do so, open a terminal, become root with ' sudo -s ', and then enter the following:. The holds will prevent you from upgrading MariaDB, so when you want to remove the holds, open a terminal, become root with ' sudo -s ', and then enter the following:.
You will then be able to upgrade MariaDB as normal e. When the mariadb-server DEB package is installed, it will create a user and group named mysql , if they do not already exist. Knowledge Base Contact Login Search. Installing MariaDB. MariaDB starting with MariaDB MariaDB until MariaDB starting with 5. MariaDB 5. If a situation as described above exists when you try to install MariaDB you will get an error like this: The following packages have unmet dependencies: mariadb-server : Depends: mariadb-server Pinning the MariaDB Repository It is possible to pin the MariaDB repository used so the packages it provides will always have an higher priority over the ones from the system repositories.
Specifying Specific Versions to Install A way to fix this is to specify the exact version of the two packages that you want to install.
