ELevate CentOS 7 to AlmaLinux 8 DNF fails

I was able to fix the pre-upgrade issues. Nothing major. However the upgrade task fails with this error

Following errors occurred and the upgrade cannot continue:
1. Actor: dnf_package_download
Message: DNF execution failed with non zero exit code.

From the resulting log, this is the cause:

2024-11-20 21:08:26.175 ERROR PID: 77320 leapp.workflow.Download.dnf_package_download: Cannot calculate, check, test, or perform the upgrade transaction.

I found an article with oracle, but I’m not upgrading to oracle and it could be a mirror issue. I’ve cleared the yum cache and rerun the upgrade. Same issue.

I found an article at doc.cloud.comwork.io which suggests it’s a disk space issue, but I have 140 G available.

I see an article w/ RedHat about it, but I don’t pay them anything so it’s useless.

Could someone point me in the direction of the cause/fix?

I think I figured it out. There were two python libraries that had conflicts. I removed them and the upgrade step completed:

python36-six
python3-simplejson
