CPU architecture issue was seen on
arm64
Expected behaviour you didn't see
Logging in via gdm should work
Unexpected behaviour you saw
Logging in via gdm stalls. When I attempt to activate manually via
homectl activate, I get an "Invalid argument" error.
Steps to reproduce the problem
I created the home partition on an sd card via something like
homectl create --image-path=/dev/mmcblk0 ...on an older version of systemd (it was a while ago, so I don't remember exactly which version). Today I upgraded systemd and restarted, and I found I could no longer activate my home directory.
