Ok. I am going to go insane if I cannot figure this out.
I work on a virtual server running Ubuntu 12.04, which I need to upgrade to 14.04. That part goes just fine. However, upon upgrading, I discovered that my server doesn't want to play nicely with OCSP anymore. Apparently Apache is changing to OCSP stapling in version 2.4, which is forcibly bundled with the OS upgrade. If I thought I could figure out OCSP stapling in a timely fashion, great. But the way I see it, I could downgrade Apache back to 2.2.22 as OCSP is unfamiliar to me at this point. I am a new SYSADMIN on the system I work on, and had little to no turnover. I am also far more familiar with RedHat than Ubuntu.
I have been doing all of my testing on a clone because I cannot bring the primary down for as long as I (apparently) needed to for testing. I have successfully installed Apache 2.2.22, but I still can't get it to work. I get a variety of errors. Apache won't restart because of abc, and once I figure those out, or mitigate them, a whole new host of errors shows up.
I am happy to provide specifics if needed, but even general advice would be fantastic.
