Issue/Bug Description
When attempting to unlock a LUKS-encrypted volume using Disks, an error
message is displayed after entering the password that reads:
Error unlocking: The function
'bd_crypto_luks_open_blob' called, but not
implemented! (udisks-error-quark, 0)
It appears upstream Ubuntu is missing a package as a dependency,
libblockdev-crypto2. Installing that package and restarting udisks allows it
to work correctly:
sudo apt install libblockdev-crypto2
systemctl restart udisks2.service
Steps to reproduce (if you know)
Create a LUKS-encrypted volume on any drive (internal or removable)
Attempt to unlock the volume.
