@Duncaen sure, I can. Here I was using 'xbps-install -Su' command, would you like to just strace it, and try to find calls around error/post log?

Currently I'm only able to downgrade linux kernel package, as I have the newest one installed today. Can you guide me how to do it, as simple ```xbps-install --force --debug /var/cache/xbps/linux5.15-5.15.131_1.x86_64-musl.xbps``` results  in error: _Package '/var/cache/xbps/linux5.15-5.15.131_1.x86_64-musl.xbps' not found in repository pool_

P.S. My guess about chmod/chown is because after each command/error, the offending file from error message *is* unpacked to /boot, but the whole command aborts while the next (exactly the same xbps-install -Su) invocation moves forward and fails on another file, then third call succeeds. I might be wrong though.
