Unexpected format of target version: 7

@anderbubble original Leapp doesn't support CentOS.
You can try ELevate project based on Leapp but with necessary patches to support non-RHEL OS

Here's the patch I was working on as an experiment, in case it's useful information.

@anderbubble As Andrew has stated above, leapp does not support CentOS and there are no plans to change that. Please look into ELevate if you need CentOS upgrades.
