Hi @davec51,
Probably you preformed a minimum install (by using the corresponding .iso image). The minimum install is just a basic running system (which doesn’t contain any GUI) and should be further adapted to your needs.
If you wish GUI, it’s very simple:
as root, run:
dnf grouplist
which lists the groups of packages, each one oriented towards a specific role.
You probably wish to install:
dnf group install "Server with GUI"
and also (if you feel more comfortable than dealing with the command prompt)
dnf group install "Graphical Administration Tools"
Reboot the machine after the installation process finished.
Regards,
Bogdan
Later edit: avoid at this moment to install “KDE (K Desktop Environment)” (from epel), because the packages are not yet rebuilt for Alma Linux 8.5; check this post
