Cannot restore from backup

Yet, here we are a year later and my HAOS x86 backup(s) just hang at a fresh install.
I may be geeky enough to get this fixed, but I shouldn’t be in this situation.
This isn’t going to fly in production as the user base grows beyond the geeks.
While I don’t agree with his aggression, I do admire his effort in telling you to fix your attitude as well, while it may work for you, it sure doesn’t work here and it sure doesn’t give any indication as to wtf is happening, or not.

It’s a spinning wheel that never ends, doesn’t give any input as to what’s failed. The file uploads fine, gets detected as a backup, so it’s at least not a totally corrupt tar file.
People shouldn’t be expected to be a super user to make this work and I’m considering that more from a permissions perspective.
