How to install a newer version of Python using apt-get?
Felix Krull runs a PPA offering basically any version of Python (seriously, there is 2.3.7 build for vivid…) for many Ubuntu releases at https://launchpad.net/~fkrull/+archive/ubuntu/deadsnakes.
Do the usual:
sudo add-apt-repository ppa:fkrull/deadsnakes sudo apt-get update sudo apt-get install python3.5
It will not overwrite your existing
python3.4 which is still symlinked as
DON’T change the symlink! There are apparently many system functions that don’t work properly with python3.5.
I tried this and afterwards couldn’t open a terminal, software updater,…
cd /usr/bin sudo rm python3
The upgrade to Wily will adapt the meta-package
python3 to point to
python3.5. I don’t expect any breakage, but at this point the foreign repository is not needed anymore. So to be really safe, you can purge the PPA before doing the upgrade.
