What were you trying to do that didn't work?
I'm converting one CentOS Stream 8 system to RHEL 8, and even after following [0] I just couldn't make convert2rhel work - both analyze and convert verb would just stop after a couple of phases without any error or message about what's wrong:
# convert2rhel convert2rhel command used: /usr/bin/convert2rhel [2024-06-24T09:48:42-0400] TASK - [Prepare: Show Red Hat software EULA] ****************************** ...

There's no information about what and/or why failed neither on screen nor in any of the log files. Only after rerunning the command with --debug it shows something actionable:

The system in question doesn't have yum installed as I removed it quite a while ago (and use dnf). I understand that this is quite a niche scenario (since the yum package is protected even if it's installed alongside dnf), but It would be great if convert2rhel complained loudly about this, as yum appears to be crucial for the conversion to work.
