type `whereis` python in your shell and see if it is on `$PATH`. If it isn't, then there's something wrong with your ubuntu distribution since ubuntu typically ships python. You could try to re-install python by putting in `sudo apt-get install python` in your shell.

Looks, like you installed python3, but somehow softlink `python` was not created.
You may try to make the link yourself. Type `sudo ln -s $(which python3) /usr/bin/python`. This will create a link called "python" to python3.
However be sure, that python3 is needed for LND, otherwise just install python from apt-get.

None of tips above worked for me, unfortunately.
