After the last release upgrade it ended on an error. I tried to finish the install and it said I needed to restart to complete the upgrade. When I rebooted it won't come up.

If I can find a thumb drive with enough space I'll try a current install and just overwrite the whole thing. I backed up /home to an external USB hard drive before I started the whole process.

Wait, duh, external USB hard drive. Going to see if I can make a bootable image on that.
