I run Ubuntu LTS on many of my servers. Most of them are just VM hosts running KVM. If I had to do it again, I'd go with Debian. Ubuntu upgrades often do strange and surprising things. I remember doing a minor upgrade with 20.04 and losing the default route! Another minor upgrade renamed network interfaces. (20.04.1 I think?) The machine was completely inaccessible remotely. Perhaps this was "my" fault because the machine had been updated several times, originally at 14.04 through various LTS releases, accumulating cruft.
