Public bug reported: Since Ubuntu 18.04 LTS, a minimal installation is possible with the Ubuntu installer. If I go for that and choose to encrypt the disk, I cannot change the password via the utility gnome-disks graphically afterwards.
Steps to Reproduce 1. install Ubuntu 18.04 LTS (daily 20180420 and Beta 2 tested) 2. encrypt the disk, while going through the installer 3. after installation: Disks (3.28.1) » (highlight) Partition 3 with LUKS (open padlock icon) » (button with two cog-wheels) Options » Change Passphrase » … Expected Results The password should be changed. Or if a software package is missing for this, it should install that. At least, a note should appear how to install/add that package. Actual Results “Error changing passphrase on device /dev/sda3: The function 'bd_crypto_luks_change_key_blob' called, but not implemented! (udisks-error-quark, 0)” Workaround sudo apt install libblockdev-crypto2 After that, a log-off was not sufficient; instead I had to restart the computer. Before I found that, I was able to change the password non-graphically thanks to <https://superuser.com/a/431832>. ** Affects: gnome-disk-utility (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1765701 Title: [min. installation] Cannot change Passphrase.
