Public bug reported: System hangs during boot with 4.4.0-45-generic if cryptab contains a valid entry. Passphrase prompt never seen. Black screen with blinking underscore in upper left corner. Repeated attempts to type passphrase have no effect.
There are two workarounds: 1) Comment out line referring the encrypted partition in /etc/crypttab and /etc/fstab. Mount the partition manually after boot completes 2) Boot in 4.4.0-42-generic which works as do earlier versions. i.e. the user provides passphrase at the prompt during boot and the system finishes booting robert@kalymnos:~$ cat /etc/crypttab spare2 UUID=498b08bb-5e6b-4ddf-8b37-e059665a34e6 none luks robert@kalymnos:~$ grep mapper /etc/fstab /dev/mapper/spare2 /spare2 ext4 defaults 0 2 ** Affects: ubuntu Importance: Undecided Status: New ** Summary changed: - Hang during boot 4.4.0-45-generic with /etc/cryptab .
