Like you i ran into the same error message after upgrading my XUbuntu to jammy (22). So i am not used to this error, but what i found may help you. All commands must be executed as root or, recommended, using a sudo prefix:
One of the installed files of the daemon package is /lib/systemd/system/ubuntu-advantage-desktop-daemon.service, the so called unit file. Trying to enable it by systemctl enable ubuntu-advantage-desktop-daemon.service results in the following error message:
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.
What i did:
systemctl disable ubuntu-advantage.service
systemctl enable ubuntu-advantage.service
systemctl disable ubuntu-advantage-desktop-daemon.service (issues error message)
systemctl start ubuntu-advantage-desktop-daemon.service
Then
systemctl -a|grep ubuntu
shows
● ubuntu-advantage-cloud-id-shim.service not-found inactive dead ubuntu-advantage-cloud-id-shim.service
ubuntu-advantage-desktop-daemon.service loaded active running
Desktop service for Ubuntu Advantage
ubuntu-advantage.service loaded inactive dead Ubuntu Pro Background
Auto Attach
After the next reboot the ubuntu-advantage-desktop-daemon.service is neither running nor loaded but can be started by systemctl start ubuntu-advantage-desktop-daemon.service.
Since i do not want commercial Ubuntu Advantage i did
systemctl disable ubuntu-advantage-desktop-daemon.service
and
systemctl disable ubuntu-advantage.service
Since you did not describe the situation the error message occurs in your terminal in detail, i cannot help you more.
