The SUSE Manager Proxy has been setup by packages as a client of the SUSE Manager.

Resolution

Please check the version of the following package:

# rpm -q python3-uyuni-common-libs

if this is python3-uyuni-common-libs-5.0.5 please downgrade the package to the most recent version from the SUSE Manager Proxy channel:

# zypper in --old-package python3-uyuni-common-libs-4.3.11-150400.3.21.6
# systemctl restart spacewalk-proxy

Cause

The package was mistakenly installed from the channel "SLE-Manager-Tools15-Updates for x86_64 SP4".
