Advanced partitioning attempts to setup encrypted / and swap partitions, attempting to proceed beyond partitioning UI results in failure to mount crypted volume as /target.
Further checks from terminal show no valid filesystem exists on the open dmcrypt volume.
Reproduction details:
- Existing windows installation partitions, consuming ~1/2 of a 1TB NVMe
- Create new 1gb EXT4 formatted, non-encrypted /boot partition
- Create new 70gb encrypted partition
+ Edit the new partition to be / and formatted ext4
- Create new 16gb encrypted partition
+ Edit the new partition to be type swap
- Click the button to continue installation
Expected results:
- Installation continues
Actual results:
- Time zone selection screen appears, but message pops up indicating a failure to mount the encrypted / volume on /target
- Unable to click 'Go Back' or 'Continue' or the 'X' at the top of the modal dialog
- Unable to click anything on the time zone selection window underneath ( greyed out )
Additionally:
- Attempts to re-use existing encrypted partitions was 100% unsuccessful
+ Tried clicking one, setting it as a raw encrypted partition, setting the password that existed on it, but the installer never presented details about that crypted filesystem's contents
+ Tried pre-opening the crypted volumes from terminal using cryptsetup, which did allow the installation to complete, but was unable to boot due to missing crypttab entries in initramfs.
