When I power on the system, I get the following messages:
firmware: failed to load i915/skl_dmc_ver1_27
WARNING: Failed to connect to lvmetad. Falling back to device scanning.
Volume group crypt not found.
Cannot process volume group crypt
cryptsetup (sda5_crypt): cryptsetup failed, bad password, or options?
Please unlock disk sda5_crypt:
whereupon I enter the encryption password and everything proceeds normally. At other times, I simply get a blank progress bar that remains until I hit the Purism key and then I get the graphic disk encryption unlock request and all proceeds normally.
I tried the “broken system upgrade” fix, but it didn’t work. I wasn’t doing anything special at the time, but I had recently installed kMyMoney as a sub for GnuCash and was working through the online banking setup. Obviously disk encryption is fine, but the boot process is corrupted.
