I'm seeing an error during the apt-get install:

E: Unable to locate package libcario2-dev

Is that a typo, should it be libcairo2-dev?

also pyenv is a command not found. Change to a python3 -m venv? Not quite sure what those steps are trying to do tbh...

according to this thread, it's a wild goose chase anyway: https://vi.stackexchange.com/questions/779/how-do-i-get-vim-to-be-able-to-run-both-python-and-python3-on-a-linux-system-in

but the workaround of apt-get install vim-gtk3 vim-gtk3-py2 is ok for now. sorry for the stream-of-consciousness comments on your nice script!

Sorry I haven't notice your comment. pyenv is used to build Python 2 and Python 3 with --enable-shared while Vim on Debian package was not compiled with that parameter.
And the command is https://github.com/yyuu/pyenv
