Don’t use Ubuntu as a server. Pretty much every server application will run happily on Debian, meanwhile Canonical keeps adding/changing shit that is Ubuntu-specific and has broken otherwise-functioning server installations. I may or may not have personal experience with this.
Ubuntu used to be the go-to, but Canonical is quickly becoming the poster child for Linux enshittification.
For servers, use Debian and never think about it again. Except the one or two times a year it should probably be rebooted because of kernel updates.
