Success!

I upgraded from Ubuntu 20.04 to 22.04 on an circa-2016 ASUS laptop using Ben's instructions in comment #41. After rebooting was prompted for password to unlock the device which worked as expected and led to the login screen and then the desktop. Opened a few apps and browsed the file system, everything seems to be working and all the files on the encrypted root and home partitions seem available!

IIRC the device had previously been upgraded from 18.04 to 20.04.

This is a laptop I regularly use, not a test device, so this was a 'real' successful upgrade in the wild. =)

Thanks all for the fix!

Hopefully prior to next LTS release the automated testing can be improved to include encrypted file systems and other scenarios as Brian mentioned in #40. Could help tighten release dates and increase user confidence (not to mention help Ubuntu devs sleep better at night!). If this issue had affected my non-techy users as part of a regular upgrade it may have torpedoed their confidence in Ubuntu and Linux by association. (Almost every non-tech I know who uses Ubuntu had it installed for them on a laptop with file system encryption enabled for privacy and security.)
