The update is fine, but that package is missing several dependencies, at
least: python-jinja2, coreutils and iproute. Try running it in a pure
environment and it will crash “guix environment --pure --container
--ad-hoc protonvpn-cli -- protonvpn -h”.

Searching the source for “subprocess.run” I find call to other binaries
which aren't listed as dependencies. Could you wrap the “protonvpn”
binary with the “PATH” of all the binaries it uses to avoid propagating
a whole lot of packages. Probably only “python-jinja2” should be
propagated.
