I've discovered a problem with the 20.04 server installer, where it crashes if the BIOS time is incorrect (in my case, because the machine doesn't have a real time clock battery installed, so it always thinks it's 2012 until it can connect to an NTP server). The issue seems to be a failed certificate validation during install. Unfortunately, I couldn't figure out how to copy the crash log off of the machine in question.
I'd like to report this bug, and I might even have the skills to work on it, but I don't really know where or how to do that. I gather that the server installer consists of a few projects... should I open an issue on the Subiquity github project?
