Generally we've had CI for the current Ubuntu LTS plus the previous Ubuntu LTS.

e126deb2de831d559c49a8c3b0f4edd1b1291bb0 in June added in 20.04 and dropped 16.04, so you can probably bisect back to work what broke it, or look at how it was being built back then and figure out what you're doing differently.
