Description:

Hello!

Whenever using dnf with my systems I get several error messages:

Invalid configuration value: failovermethod=priority in
/etc/yum.repos.d/pgdg-redhat-all.repo; Configuration: OptionBinding with id
"failovermethod" does not exist

This seems to occur after an update of dnf. Problem is also mentioned in an
publically available ticket at RedHat's bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=1961083

So my suggested fix would be: remove the unsupported option from the
repo-file.

THX in advance an with regards,
Peter.
