I have an external hard drive that I have been using for encrypted backups. It's been working find with xubuntu 16.xx LTS. Now I've updated to 18.04 and can't mount the drive. cryptsetup 2.0.2 My notes from last time say to do this: chmod 0400 /root/keyfile cryptsetup luksAddKey /dev/sdb /root/keyfile Which returns: If I try to mount from the file manager (thunar) I get this: More: Cannot use device /dev/sdb which is in use (already mapped or mounted) cryptsetup luksClose /dev/sdb Device sdb not found cryptsetup --debug luksAddKey /dev/sdb /root/keyfile # cryptsetup 2.0.2 processing "cryptsetup --debug luksAddKey /dev/sdb /root/keyfile" # Running command luksAddKey. # Locking memory. # Installing SIGINT/SIGTERM handler. # Unblocking interruption on signal. # Allocating context for crypt device /dev/sdb. # Trying to open and read device /dev/sdb with direct-io. # Initialising device-mapper backend library. # Trying to load any crypt type from device /dev/sdb. # Crypto backend (gcrypt 1.8.1) initialized in cryptsetup library version 2.0.2. # Detected kernel Linux 4.15.0-23-generic x86_64. # PBKDF pbkdf2, hash sha256, time_ms 2000 (iterations 0), max_memory_kb 0, parallel_threads 0. # Reading LUKS header of size 1024 from device /dev/sdb # Key length 32, device size 195813072 sectors, header size 2050 sectors. # PBKDF pbkdf2, hash sha256, time_ms 2000 (iterations 0), max_memory_kb 0, parallel_threads 0. # Interactive passphrase entry requested.
