This morning, when I SSHed into my droplet, it said that there was a new version of Ubuntu available, so I decided to upgrade. Everything seemed to go well and I didn’t overwrite any files that were locally modified (like /etc/nginx/sites-available/default).
After the upgrade, when trying to visit my site, I got a 404 error from nginx. I tried restarting nginx, PHP and MySQL, without success. I also tried apt-get update and apt-get update --fix-missing, but also without success.
Any ideas on what might be causing it and how to remediate it?
