I installed anaconda and run 'sudo apt-get update && sudo apt-get dist-upgrade' on an Ubuntu 16.04 system. I upgraded pip inside an Anaconda environment and also used the 'sudo apt-get autoremove' command as well but not sure if those are related to the problem. So the problem is this:
For some reason the python3 symlink is dead (I'm assuming it previously pointed at python3.6). Is it safe for me to simply use update-alternatives to point the python3 symlink at /usr/bin/python3.5?
Thanks any help appreciated.
Edit: Also note that I found the Jonathonf PPA is being used on this system to get Python3.6. I found information on the internet that this repo is no longer active. Could that be the soure of the problem?
