How to fix: ubuntu 19.04 cannot upgrade to 19.10 error "Your python3 install is corrupted. Please fix the '/usr/bin/python3'"

Question

I tried to run the distribution upgrade on Ubuntu 19.04: sudo do-release-upgrade

I got the error:

Can not upgrade`

Your python3 install is corrupted. Please fix the '/usr/bin/python3' 
symlink.

Checking the symlinks:

ll /usr/bin/pyt*`
/usr/bin/python -> /usr/bin/python3*
/usr/bin/python2 -> python2.7*
/usr/bin/python2.7*
/usr/bin/python3 -> /usr/bin/python3.7*
/usr/bin/python3.7*
/usr/bin/python3.7m*
/usr/bin/python3m -> python3.7m*

Answer 1

The issue is not with the /usr/bin/python3 symlink, but with /usr/bin/python

To correct, for 19.04, I ran

sudo ln -sf /usr/bin/python2.7 /usr/bin/python
