Yes, I don't have the openssl package installed which contains /etc/ssl
Looks like the Ubuntu package should have openssl as a dependency
and they left it out.
What should I be looking for in error_log. Doesn't seem to contain
anything informative
and I have LogLevel at debug2
I can connect to http://servername:443 but trying
to add a printer still results in same Upgrade message 426. Trying
to start over seems to result in delays again, i.e, I can not connect
to http://servername:443 nor https://servername.
/etc/init.d/cupsys restart
lsof -i
cupsd 368 cupsys 0u IPv6 69516 TCP *:ipp (LISTEN)
cupsd 368 cupsys 2u IPv4 69517 TCP *:ipp (LISTEN)
cupsd 368 cupsys 3u IPv6 69518 TCP *:https (LISTEN)
cupsd 368 cupsys 4u IPv4 69519 TCP *:https (LISTEN)
I think I'll try to build from the original source from www.cups.org
and see what I get there. At least it starts up as root. I think
Debian/Ubuntu
has patched your source somehow to prevent it from starting up as root...not
really sure.

ps. Perhaps there is a way to run strace that might help?
