I wanted to try #Mobian#Trixie on my #Librem5 again as I got a way to go back to #pulseaudio to as a work around to missing echo cancellation support in #pipewire (Thanks to @dos ). So I went ahead and ran the usual apt dis-upgrade way (in hindsight, may be gnome software was a better option). But I got locked out of the session as upgrade was progressing. So I had to force shut down and then use #JumpDrive to repair it from my laptop.
@dos I had not setup ssh though. Since I had to do this many times already, it was kind of okay. Though I got to document it now only.
