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.
At the top of the screen you can see errors from LVM setup where it's searching for a volume group that's not there. I have absolutely zero experience with gnuinos, so no idea how that could've happened, but at some configuration file (I'd look from fstab first) there's a mention of gnuios-vg and the actual device name is something different.
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.
Busybox is a minimal shell. You can try and find out more about what happened to sda5 and its file system. Filesystem UUIDs could help prevent this, if it decrypted fine, but I have no idea where they go on this setup
