I had to point our mirror list to
archive.debian.org to make upgrades
work again. I installed this distro (debian 8 jessie) four years ago,
in spring 2015. It's now deprecated and will only get security updates
for another year. As soon as they release Debian 10 Buster (hopefully
in a month or two) I will want to migrate
sudoroom.org to a new VPS.
