With the spacewalk-common-channels command you can add the appropriate channels. At the command prompt on the SUSE Manager container host, as root, execute the following command. Ensure you specify the correct architecture:

mgrctl exec -- spacewalk-common-channels \
-a <architecture> \
<base_channel_name> \
<child_channel_name_1> \
<child_channel_name_2> \
... <child_channel_name_n>

If automatic synchronization is turned off, synchronize the channels on the container host with the following command:

mgrctl exec -- spacewalk-repo-sync -p <base_channel_label>-<architecture>

确保同步已完成，然后再继续操作。
