Dear Chris,

installing Python3 via apt is not possible, as it returns that Python is already at the most recent version (3.6.7-1~18.04). I opened a thread on the official Mate forum to have information about Python compatibility, maybe they can help me on this side. If I get some info that might be of use to other SurfIce users, i will post them here.

In the meantime, I tried solution 2 (in my case I used /usr/lib/python3.6/config-3.6m-x86_64-linux-gnu/libpython3.6m.so) and it seems to work fine! So, I would say problem solved for me, but, as I said, if I gather some info useful for others I will report them.

Thank you so much for your help, and for this great software.

Lorenzo
