I was having some issues with my laptop connecting to wifi, so I decided just to reinstall the OS. I made a backup with Duplicity and moved it to my phone, made a fresh install of Ubuntu 18.04, then moved the backup back onto my laptop to restore.
I've done this before, but this time things didn't go as smoothly. I went through the restore dialogues, and as it started restoring there was an error:
Restore Failed
Failed with an unknown error.

I need to fix this urgently, and I'll provide updates if I discover anything, but I'll I can really do is look up the error and see if anyone else has experienced it. I'm not sure what's going on.
I ran
LANG=C DEJA_DUP_DEBUG=1 deja-dup --restore
which, after successfully detecting all my old snaps (it said DUPLICITY INFO 'home/user/snap/app/...), created the following output with errors. I really need my files back, and I don't know what happened to create such a huge error.
