I just tried installing Gnuinos and after finishing on first bootup this is what I get. I have tried on both Runit and SysVinit so I don’t think it’s do do with init issues. Any ideas on what the issue is and how to fix ? This system works fine with Trisquel so I know it’s libre friendly.
Are you using full disk encryption? I assume you were prompted to unlock the disk, and got this error after unlocking the disk?
I recently got a problem where the disk’s uuid reference somehow doesn’t match with the actual uuid, leading to failed boot. A bit similar with this stackoverflow question, which might give you a pointer to start.
