Several times I have tried to remove BAD UPDATES with no success.

Comment 1 Marek Blaha 2021-07-21 06:03:15 UTC

This is usually due to the fact that Fedora Updates repository only contains the latest versions of released updates. Consider following transactions:

1. install gnucash-0:4.4-1.fc34.x86_64 from Fedora repo
2. update to gnucash-0:4.6-1.fc34.x86_64 from Fedora Updates
3. update to gnucash-0:4.6-2.fc34.x86_64 from Fedora Updates

Now if you wanted to undo the transaction #3 it would mean downgrading the gnucash package to version 4.6-1. But this package is no longer present in repositories (because it was replaced by newer 4.6.-2 update), thus the error message - Cannot find rpm nevra "gnucash-4.6-1.fc34.x86_64".

You can kind of workaround it by using `local` plugin (dnf install dnf-plugin-local) which will automatically maintain a repository on the local filesystem containing all the packages dnf ever downloaded (also updates no longer present in official repositories). See https://dnf-plugins-core.readthedocs.io/en/latest/local.html for the documentation.

The other possibility is to find older build of the package in koji (e.g. https://koji.fedoraproject.org/koji/buildinfo?buildID=1776354 for gnucash) and download and install it manually.

But from dnf perspective this is not a bug - we cannot install package that is not available. Please do not hesitate to re-open the bug if the cause was different in your case.
