I usually use Timeshift to do a manual system backup before system upgrades. Today I forgot, and of course something went wrong…
At boot, the system hangs after I input my LUKS password. I can boot from USB and mount the encrypted partition with Dolphin without problems.
I have a dual boot setup (Windows 10) with these partitions, as listed by KDE Partition manager:
/dev/nvme01p1, fat32, "EFI system partition" (100 MiB) /dev/nvme01p2, unknown, "Microsoft reserved partition" (16 MiB) /dev/nvme01p3, ntfs, "Basic data partition" (232.65 GiB) /dev/nvme01p5, ext4, No mount point shown, but this is my / (42.76 GiB) /dev/nvme01p6, luks, No mount point , but this is where /home is (639.76 GiB) /dev/nvme01p7, linuxswap (38.09 GiB) /dev/nvme01p4, ntfs (499 MiB) unallocated, unknown (1.32 MiB)
I have met the same problem before, but then just doing a hard reboot would allow me to restart. This time, starting over does not help. I have tried waiting for more than 5 minutes after typing my password to see if the initial de-encryption was slower (usually it’s about instantly, max a few seconds, to decrypt).
So, what to do next? Can I remove encryption, restart and then re-enable encryption?
