Backup fails after upgrading server from 2.3.8 to 2.4.9

Lots of “Error setting file time” warnings but I had those on 2.3.8 as well. What’s new is the error at the end “Syncing file system failed. Backup is not completely on disk. Operation not permitted (code: 1)”

Running the server as root did not solve the problem this time. Fedora 30 (installed package manually…), mergerfs. Will try downgrading for now

P.S. Pressing Ctrl+C at the urbackupsrv run console now results in a segmentation fault
