Try installing Lubuntu before you part out the machine. The Server 22.04 failure likely is a consequence of an absence of BIOS kernel graphics support. Lubuntu is brilliant on old machines and may install notwithstanding the Server debacle. If so, you'll have a bonus in the form of a GUI, if you want it. If not, it's easy enough to uninstall or, as lightweight as it is, not even bother and just get on with the rest of the configuration.
