Environment

SUSE Manager Server 4.2

Situation

Yum Update on rhel 8 clients fails with the following post-bootstrapping error:

[root@redhat8-test ~]# yum update
Updating Subscription Management repositories.
rhel--8-nonprod-171122-rhel8nprd171122-std-res-x86_64-server-8-baseos                                                         30 kB/s | 3.9 kB     00:00
Errors during downloading metadata for repository 'susemanager:rhel--8-nonprod-171122-rhel8nprd171122-std-res-x86_64-server-8-baseos':
  - Status code: 403 for https://dnkgevelsmrp011.velux.org:443/rhn/manager/download/rhel--8-nonprod-171122-rhel8nprd171122-std-res-x86_64-server-8-baseos/repodata/repomd.xml
Error: Failed to download metadata for repo 'susemanager:rhel--8-nonprod-171122-rhel8nprd171122-std-res-x86_64-server-8-baseos': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried

Resolution

Copy the susemanagerplugin.py file from "/usr/lib/python3.10/site-packages/dnf-plugins/susemanagerplugin.py" to "/usr/lib/python3.6/site-packages/dnf-plugins/"

#cp /usr/lib/python3.10/site-packages/dnf-plugins/susemanagerplugin.py  /usr/lib/python3.6/site-packages/dnf-plugins/

Cause

The bootstrap was failing due to a missing file in the python3.10 directory, and was initially fixed after creating a symlink for /usr/lib/python3.6 and /usr/lib/python3.10, however, the error 403 persisted during client update.

The underlying cause of the bootstrap issue and update error 403 was the missing file susemanagerplugin.py at /usr/lib/python3.6/site-packages/dnf-plugins/.
