Not working with pylsp installed from Snap in Ubuntu 18.04

I'm using ide-python with Atom 1.58.0 and Ubuntu 18.04.
I've installed Python language server from the Snap store, the executable pylsp is correctly addressed from a terminal (e.g. if I do `pylsp -h` or `pylsp -v`).
The version of pylsp should be 1.0.1.

However, when I start Atom I get the error "Unable to start the Python language server" etc.

In the ide-python settings the executable string is the default (`pylsp`).

Am I missing something?
Is it supposed not to be working this way? (I'd prefer not to use pip, to not have to take care of updates).

Start by reproducing the failure with Atom 1.58.0 on Ubuntu 18.04, ide-python's default `pylsp` executable, and pylsp 1.0.1 installed from Snap. Compare the environment used by Atom with the terminal where `pylsp -h` works; done means the Python language server starts successfully from ide-python.
