#5 0.678  One of the configured repositories failed (Unknown),
#5 0.678  and yum doesn't have enough cached data to continue. At this point the only
#5 0.678  safe thing yum can do is fail. There are a few ways to work "fix" this:
#5 0.678 
#5 0.678      1. Contact the upstream for the repository and get them to fix the problem.
#5 0.678 
#5 0.678      2. Reconfigure the baseurl/etc. for the repository, to point to a working
#5 0.678         upstream. This is most often useful if you are using a newer
#5 0.678         distribution release than is supported by the repository (and the
#5 0.678         packages for the previous distribution release still work).
#5 0.678 
#5 0.678      3. Run the command with the repository temporarily disabled
#5 0.678             yum --disablerepo=<repoid> ...
#5 0.678 
#5 0.678      4. Disable the repository permanently, so yum won't use it by default. Yum
#5 0.678         will then just ignore the repository until you permanently enable it
#5 0.678         again or use --enablerepo for temporary usage:
#5 0.678 
#5 0.678             yum-config-manager --disable <repoid>
#5 0.678         or
#5 0.678             subscription-manager repos --disable=<repoid>
#5 0.678 
#5 0.678      5. Configure the failing repository to be skipped, if it is unavailable.
#5 0.678         Note that yum will try to contact the repo. when it runs most commands,
#5 0.678         so will have to try and fail each time (and thus. yum will be be much
#5 0.678         slower). If it is a very temporary problem though, this is often a nice
#5 0.678         compromise:
#5 0.678 
#5 0.678             yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
#5 0.678

Thanks for this suggestion. The python3.11 container is based on Debian, whereas most of our user community would prefer a RedHat version. I suggest to change it to be based on an alma9 image instead.

For now, I've switched to ubi9/python-311. Let me know if Alma would be a better fit.

[egede]

I would still prefer alma9. The other image you use here is more aimed at web servers which is not the use case here.

Switched to alma9.
