Your python3 install is corrupted. Please fix the '/usr/bin/python3' symlink [duplicate]
I believe this is a know issue.
The suggested workaround is to remove the python’s binary in /usr/bin and then to create a symlink and perform the upgrade:
sudo rm /usr/bin/python
sudo ln -s /usr/bin/python2.7 /usr/bin/python
sudo apt upgrade
do-release-upgrade
Let me know how it goes.
Solution:
I pointed python3.6 to python3
Use Ubuntu pkgd python or python3 and not the upgraded versions!
Thanks all for the help. Sometimes you have to sweat all day to think of a small minor adjustment.
