2.1.1. Identifying Channel labels
-
In the SUSE Manager Web UI, in the sidebar navigate to
. -
This page displays the
Channel Name
. If you select the link for a channel name, you will see the field forChannel Label
. -
Identify the channel, and child channels, to be removed.

You can get a list of channels by running the following command:
spacewalk-remove-channel -l
2.1.2. Verify channel system subscriptions
-
In the SUSE Manager Web UI, in the sidebar navigate to
. -
Locate
Systems
column on the right. -
Check the
Systems
column for the channel, or any child channels, that you want to remove.
-
Run the following command:
spacecmd -- softwarechannel_listsystems <Channel Label>
2.2. Removing channel
A channel, with its metadata, can be removed in the SUMA command line by using the spacewalk-remove-channel
command. This command does not remove the packages themselves from the filesystem.
Removing packages from the filesystem is described in [cleaning-up-channel-packages].
2.2.1. Removing an individual channel
-
To remove an individual channel run the following command:
spacewalk-remove-channel -c channel-label
+
. To remove multiple channels at the same time, use -c
flag for each channel, followed by the channel-label
.
For example:
+
spacewalk-remove-channel -c channel-label1 -c channel-label2
2.2.2. Removing a parent and all its child channels
spacewalk-remove-channel -a sles12-sp5-pool-x86_64
2.2.4. Clean the packages from the filesystem
# spacewalk-data-fsck -r -S -C -O
+
The final cleanup command can take several minutes, or even hours to complete. |
