Problem installing cups-devel on Rocky 8.6

True yes I did check that, but the warning itself is enough unless you are doing that kind of building then it’s not needed. Either way, I tried with and without it enabled and was able to get gnutls-devel installed, which leads me to believe either:

  1. System not quite up-to-date with perhaps gnutls itself.
  2. System was maybe upgraded and in a bit of a mess with package conflicts.

Another option that could be tried is:

dnf clean all
dnf reinstall gnutls

to force it to pull it from a repo and install over the top of the existing one. As mine doesn’t conflict with the gnutls-devel, despite having that hmac file inside both packages.
