I mean, the "pve-kernel-5.3" package is just a meta package intended to pull in the newest real kernel, but the "Depends" really should pull it in.
Is the "real" kernel installed:(check the second line "Status")Code:dpkg -s pve-kernel-5.3.10-1-pve
How did you rolled back to 5.0?

This package contains the linux kernel and initial ramdisk used for booting
Just updated the grub config, the other server I tested it on is fine, but this one the kernel files don't exist even after it says it installed it..
