First, Is ONL still a viable project? and if not what are people using now?
I am not sure if I need updated packages or not, whether they differ from a mainline Debian distribution or not, and whether I should be resolving this by rebuilding the installer rather than running straight to the list with my questions.
However, I thought I would put it out there to ask whether anyone knows how I could get in touch with the people who run
opennetlinux.org to see if they might be able to restart certbot and fix the permissions on the
apt.opennetlinux.org site.
