Im a fairy new user at Linux.
I have Ubuntu 18.04 on a host at paperspace.
I'm following this guide: https://www.teknotut.com/en/install-vnc-server-with-gnome-display-on-ubuntu-18-04/
Beside that I installed ZeroTier for VPN access.
Everything in the guide worked fine except this line:
sudo systemctl enable gdm
I get the following error:
The unit files have no installation config (WantedBy, RequiredBy, Also, Alias
settings in the [Install] section, and DefaultInstance for template units).
This means they are not meant to be enabled using systemctl.
Possible reasons for having this kind of units are:
A unit may be statically enabled by being symlinked from another unit's
.wants/ or .requires/ directory.
- A unit's purpose may be to act as a helper for some other unit which has
a requirement dependency on it.
- A unit may be started when needed via activation (socket, path, timer,
D-Bus, udev, scripted systemctl call, ...).
- In case of template units, the unit is meant to be enabled with some
instance name specified.
How can I fix this?
