When I updated the INDI library, I got a message that Python 3.6 could not be installed, saying: failed to fetch ppa.launchpad.net/jonathonf/python-3.6/u...6.04.york3_amd64.deb 403 Forbidden [IP: 91.189.95.83 80]. Is this a problem? And if yes, does anyone know a fix? I tried to check my version of python, with 'python --version', which gave me 2.7.12 With 'python3 --version' it gave me 3.5.2 So a python 2 and 3 seem to be co-installed. Is that a problem? Thanks for any insight.Read More...
