I want to confirm the problem and the workaround for the benefit of other people who will come across it, since it wasn't easy to fing.
If you are using encrypted disk and the fcsk is being executed before or during the cryptsetup password prompt during plymouth or more precise mountall, it is more likely due to the fact that your encrypted disks are references in the /etc/fstab using UUID rather than using the mapper paths. The workaround is to edit /etc/fstab and refer the encrypted disks using mapper paths, e.g. # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 UUID=cfc42d03-788c-4ce8-a5bf-b1ed12e286c0 /boot ext4 relatime,discard 0 2 #UUID=5c18efc3-d3eb-4e2e-a8a1-c4be8b7cacb5 / ext4 relatime,discard,errors=remount-ro 0 1 /dev/mapper/root_crypt / ext4 relatime,discard,errors=remount-ro 0 1 #UUID=151192b4-2f9c-479b-8b4d-62bb38cef7ee /home ext4 relatime,errors=remount-ro 0 1 /dev/mapper/home_crypt /home ext4 relatime,errors=remount-ro 0 1 #UUID=cc988cfb-3bf9-41b4-9cc4-11ff5fdf089c /data ext4 relatime,errors=remount-ro 0 2 /dev/mapper/data_crypt /data ext4 relatime,errors=remount-ro 0 2 #UUID=60c8d952-f3dc-4d15-8eac-c97718de9f6a /archive ext4 relatime,errors=remount-ro 0 2 /dev/mapper/archive_crypt /archive ext4 relatime,errors=remount-ro 0 2 #UUID=47A7-EF59 /media/bootkey vfat utf8,umask=007,gid=46 0 1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/719563 Title: mountall: fatal error: cannot open /dev/mapper/crypthome_unformatted To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/719563/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
