Trying to migrate to Rocky 8 from CentOS 8.5.2111

[rpyne]

Trying to migrate my mail server to Rocky. Fortunately I made a full clone of the VM so at least I'm not completely dead in the water.

Error running pre-update. Stopping now to avoid putting the system in an unstable state. Please correct the issues shown here and try again.

An error occurred while we were attempting to convert your system to Rocky Linux. Your system may be unstable. Script will now exit to preve nt possible damage.

It appears that there are certain 3rd-party repos that no longer work with CentOS 8.5 because they are expecting newer packages than those provided by that old release of CentOS, so it's causing the pre-update to fail.

The pre-update is done before any changes are made to your system so that a failed update will stop the migration before damage is done, your system should not need to be restored from your snapshot at this stage, but it's a good idea that you took one anyways.

Can you try this:

dnf repolist --enabled remi\* epel\* # make a note of the resulting repos
dnf config-manager --disable epel\* remi\*
migrate2rocky -r
dnf config-manager --enable <repos that you noted in the first step above>
dnf update

Let me know if it works, if so I'll make a change to migrate2rocky that I'd like you to test at that point as well.

Thank you. Other than some file conflicts with ImageMagick, that worked perfectly. I had to remove ImageMagick and ImageMagick-libs and re-install them manually.

[pajamian]

Thanks for the feedback. I will work on an update that does these steps automatically and get back to you for testing.
