@PRK08 The root cause of the issue is that you are currently running on an unsupported/old version of ubuntu [16.04] where some of the packages from the ubuntu repository are out of date or no longer supported. This is an issue with the ubuntu repo and not specifically with FOG.

@salted_cashews said in Is a direct upgrade possible in this scenario while retaining all previous configurations and images?:

To be honest, I’m not 100% sure how our guy knew that was causing a problem.

People with even some Linux experience normally check free space as a first-step in troubleshooting. Glad you got it figured out.
