As usual, please ALWAYS attach y2logs generated with the supplied 'save_y2logs' script. I am not going to reverse-engineer all that stuff that would be helpful here from just a lone y2logs file. It frustrates me to no end that I have to keep telling this even to people who have been working with the system for so many years. https://en.opensuse.org/openSUSE:Report_a_YaST_bug#I_attached_/var/log/YaST2/y2log_to_a_YaST2_bug,_and_still_I_am_asked_to_attach_y2logs._Why? In this case, I would have looked at the zypper history, the rpm-qa file and the storage setup in storage/ and storage-inst/. One suspicious thing here, though: >> y2-01-partitioner.log: 2022-04-09 17:18:11 <1> linux.fritz.box(3760) [Ruby] >> y2storage/storage_manager.rb(configure_snapper?):513 >> Not a fresh installation. Don't configure Snapper. >> >> y2-06-partitioner.log: 2022-06-09 13:57:16 <1> linux.fritz.box(11117) [Ruby] >> y2storage/storage_manager.rb(configure_snapper?):513 >> Not a fresh installation.
