What were you trying to do that didn't work?

Leapp fails with a counter-intuitive message concerning the GPG keys that cannot be checked. We do see it's in fact related to repositories that are not seen thanks to the below error message:

Details: No UsedTargetRepositories facts

In both customer cases, it appears the issue was related to overlayfs + xfs, using the below command fixed the issue:

# export LEAPP_OVL_IMG_FS_EXT4=1
