Ubuntu 22.04 - NFS fail to start due to missing depencies - systemd-networkd-wait-online.service and proc-fs-nfsd.mount fail to start as well [duplicate]

I'm trying to install NFS for my VPS server however it fails to start - it shows that is due to missing dependencies:

sudo systemctl status nfs-server

nfs dependencies list:

systemctl list-dependencies nfs-kernel-server

It seems that proc-fs-nfsd.mount and systemd-networkd-wait-online.service are missing.

It seems that nfsd doesn't start because the OS can't read nfsd files.

And systemd-networkd-wait-online.service fail with exit-code.

I googled about it and it seems that those dependencies are missing in some images on web servers and the only way is to install a new image with the dependencies installed.

Is there some way to install those dependencies and make NFS work without formating the system?

EDIT: Changed the ubuntu version on the title and add log text for commands
