this is probably a consequence of the problem with tumbleweed-cli. When trying to install snapshot 20231020 zypper wants to downgrade librav1e0 and then asks me to insert a cd...

The following package is going to be downgraded:
librav1e0

1 package to downgrade.

For the moment I have locked librav1e0. I tried to remove the package and then reinstall it, but removing the package would result in the removal of KDE :-(.

The following 3 patterns are going to be REMOVED:
kde 20230801-1.1
kde_imaging 20230801-1.1
kde_plasma 20230801-1.1

189 packages to remove.
After the operation, 1.8 GiB will be freed.

I found that I have two versions of librav1e:

Any idea of how to fix this?
