yeah, good idea. IMO that's even the better place to fix this than the
package control file.

IMO this is a bit weird wording. General failure can be much different things.
E.g., this sounds like it would help to install xauth for any error even if no
ssh X forwarding is involved at all.

Rather state the exact use case and requirements. Something short along the lines
of:

HINT: If you want to forward the simulator window over SSH, you need to install
the `xauth` package on the {pve} node.
