General information about the channel and its parent if applicable. This summary, description, and architecture is also displayed when clicking a channel.

In addition, Per-User Subscription Restrictions can be set globally by Uyuni administrators and channel administrators. By default, any user can subscribe channels to a system. To manage user permissions, select Only selected users within your organization may subscribe to this channel and click Update. The Subscribers tab appears. Click it to grant specific users subscription permissions to a channel. Uyuni administrators and channel administrators can always subscribe any channels to a system.

Only customers with custom base channels can change their systems' base channel assignments via the Uyuni Web interface in two ways:

Note

The assigned base channel must match the installed system. For example, a system running SUSE Linux Enterprise 11 for x86_64 cannot be registered to a SUSE Linux Enterprise 12 for s390x base channel. Use the files /etc/os-release or /etc/SuSE-release to check your product, architecture (try uname -a), version, and patch level.

On the Managers page, you can check which users are authorized to manage the selected channel.

Real name and e-mail address are listed with the user names. Organization and Channel administrators can manage any channel. As a Uyuni administrator you can change roles for specific users by clicking the name. For more information on user management and the User Details page, see Chapter 17, Users.

The Patches page lists patches to be applied to packages provided in the channel.

The list displays advisory types, names, summaries, and issue dates. Clicking an advisory name takes you to its Patch Details page. for more information, see Section 11.2.2, “Patch Details”.

This page lists packages in the channel. Clicking a package name takes you to the Package Details page.

This page displays a set of tabs with information about the package, including architectures on which it runs, the package size, build date, package dependencies, change log, list of files in the package, newer versions, and which systems have the package installed. Download the packages as RPMs.

To search for a specific package or a subset of packages, use the package filter at the top of the list. Enter a substring to search for package names containing the string. For example, typing dd in the filter might return: dd_rescue, ddclient, and uuidd. The filter is case-insensitive.

The list displays system names and their system type. Clicking a system name takes you to its System Details page. For more information, see Section 7.3, “System Details”.

List of systems eligible for subscription to the channel. This tab appears only for child channels. Use the check boxes to select the systems, then click the Confirm and Subscribe button on the bottom right-hand corner. You will receive a success message or be notified of any errors. This can also be accomplished through the Channels tab of the System Details page. For more information, see Section 7.3, “System Details”.

This page lists the settings made during channel creation.

Uyuni administrators and channel administrators may alter or delete any channel. To grant other users rights to alter or delete this channel, check the box next to the user’s name and click Update.

Channel managers can list, remove, clone, and add patches to their custom channel. Custom channels not cloned from a distribution may not contain patches until packages are available. Only patches that match the base architecture and apply to a package in that channel may be added. Finally, only cloned or custom patches may be added to custom channels. Patches may be included in a cloned channel if they are selected during channel creation.

The Sync tab lists patches that were updated since they were originally cloned in the selected cloned channel. More specifically, a patch is listed here if and only if:

To make the two channels identical, click the Merge Differences button. In the next dialog, resolve any conflicts. Preview Merge allows you to review the changes before applying them to the channels. Select those packages that you want to merge. Click Merge Packages then Confirm to perform the merge.
