Background : needing libuv-devel when AppStream/Devel versions were not in sync I installed modular libuv 1.36 from epel-modular. Subsequently when AppStream/Devel synced at 1.38 I had difficulty removing evidence of 1.36 due to /var/lib/dnf/modulefailsafe. dnf clean all didn't help there. What is the correct way to clean up modulefailsafe/ so that it unblocks non-modular packages? I had even removed all reference to EPEL repos but didn't realise the existence of the /var/lib/dnf/modulefailsafe/ lock files. Cheers Anthony
