I'm guessing that you didn't set this up on a Raspberry Pi with the OctoPi image. If so, then you'd have an
~/.octoprint folder that's used for OctoPrint's configuration files and a
~/scripts folder for various things like
welcome, etc. I'm pretty sure it was expecting to see that first folder when it tries to bring itself up. (Or perhaps it was thinking that this would be
~/oprint/lib/python2.7/site_packages or similar where the virtual environment was expected to be.)
So basically, your setup isn't at all what we're used to seeing.
So basically, if this was running fine, you had a power outage and now it's not running fine then the usual problem is a trashed file system. Consider restoring from backup.
Assuming that you don't have that, consider optionally buying a Raspberry Pi 3B, installing from the OctoPi image and get things running again. It's up to you whether or not you want to re-use that microSD card but I'd invest another $8 in a replacement for that.
