Using Ubuntu 20.04 on a XPS 15 9560, I installed the system76-power package to disable the GPU at will as I don't need it 90% of the time. It worked flawlessly for a few months but now I have a conflict between it and a nvidia-prime package (probably coming from the nvidia-driver-440/focal-updates 450.66-0ubuntu0.20.04.1).

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
system76-power : Conflicts: nvidia-prime
E: Broken packages

How do I fix this conflict?

I should mention I can't upgrade with apt as it's blocking the overall process (I could upgrade individual packages, but I'd prefer fixing the issue first).

I have no memory installing nvidia-prime but it might have been auto-installed by the driver utility.

Remove nvidia-prime with sudo apt remove nvidia-prime. If system76-power depends on it (it looks like it) remove both. If you've removed both: upgrade the system and reinstall system76-power, else upgrade only.

I'd always try not to use any force flags..
