Tried to make python3 by default in ubuntu, executed the command: sudo ln -sf python3 /usr/bin/python . Forgetting that many most programs are written in python2.7. Tried to do: sudo ln -sf python2.7 /usr/bin/python , something worked, but something didn't. For example, modules installed through pip work terribly

    Do not replace python with python3. Many system parts and utilities use python2 and in the case of a replacement interpreter will crash with errors. - m9_psy

To select the correct version of the interpreter, the correct solution would be to specify it in the first line of the .py file:

 #/usr/bin/env python3

    Run: sudo ln -sf python3 /usr/bin/python everything worked for me after that.

    • minus. Do not touch the system python on ubunt - this is a good way to render it inoperative. You can create for yourself (for example, in ~/bin/ ) a python link that points to the desired version, but /usr/bin/python should not be touched (what apt put there, it should be). - jfs
