Deciphering leapp/elevate error - RSA/SHA1 packages?

One of my boxes runs AlmaLinux 8.7. Now that the semester is over (when I can afford to have things break, at least a little…), was considering the upgrade from AlmaLinux 8 → 9.

Ran through the leapp preupgrade, and only had one ‘inhibiting’ error (mixed in with 6-7 ‘warnings’, which I’ll largely ignore for the time being).

The 'inhibiting error was:

  Upgrade has been inhibited due to the following problems:
      1. Detected RPMs with RSA/SHA1 signature

Read the report, and it looks as though there are 12-16 RPMs with the old signature - almost all having to do with ‘multimedia’, and (I suspect) coming out of rpmfusion-nonfree.

What isn’t really clear from the report is what I am supposed to do about it – simply erase all the offending RPMs and then, possibly, re-installing after the upgrade? Or some such.

Thanks in advance…

Well, solved my own problem. I decided in the end to follow my own proposal, and blew away all the RSA/SHA1 packages. Then, a couple of incompatible grub-devel files, and an hour later, Bob’s yer uncle, and upgrade from 8 → 9 completed.
