19.04 Ubuntu just died on me today (I know some expert could have gotten in working). Apparently 19.04 support ended and someone took down the servers. So trying to update would tell me something about the servers having no release file. And they wouldn't let me update to 20.04 until I patched 19.04. I never modded anything. Whatever broke it broke itself. I searched the net for answers but my search foo sucked. Someone said download the 19.04 ISO and extract the sources.list file out. I did, it had different repos but got the same errors (with the source urls pointing to the new places of course)
So, 8 hours later I just finished reformatted the drive and installed 20.04
Yep, Linux is painless :rolleyes:
