As said I am currently updating the Wiki page, but the instructions are there 
(alhtough somewhat scrambled ATM) how to run python-ly from its own Git 
repository (which can also be downloaded).

I have the impression that installing packages through pip does not work 
properly, so my recommendation (which I am currently formulating in the Wiki 
page to be fully clear) for Ubuntu 16.04 (didn't check 16.10 and 17.04) is to 
install everything except python-ly and frescobaldi through apt and 
download/clone these two from Github.
Linux Mint 18.3 is the same.
