Public bug reported:
I report this, because the problem has occurred several times during
recent upgrades:
A new kernel was installed during the upgrade, but the accompanying
kernel modules were not. As a consequence, the twofish modules were
missing, and encrypted volumes did not mount anymore. This resulted in
the error messages:
[ 366.866643] device-mapper: table: 253:0: crypt: unknown target type
[ 366.867506] device-mapper: ioctl: error adding target to table
lsmod and /proc/crypto revealed, that the twofish modules were not
loaded. Off course they were not, because
/lib/modules/4.10.0-37-generic/ did not exist. Apparently, linux-image-
extra-4.10.0-37-generic had not been installed alongside linux-
image-4.10.0-37-generic during the most recent upgrade. After manually
installing linux-image-extra, the encrypted volume mounted without
problems.
The package linux-image-extra should always be installed automatically
with a new kernel, if it was installed for the old kernel, to avoid this
and similar problems.
