Public bug reported:
This is after a reinstall of python 3.6.
The reason this was reinstalled is trying to fix an upgrade error with
do-release-upgrade (or with the gui) resulting in a python3 symlink corrupted
error. This is with default python 3.6 of ubuntu 18.10.
$ lsb_release -rd
Description: Ubuntu 18.10
Release: 18.10
$ apt-cache policy python3.6
python3.6:
Installed: 3.6.8-1~18.10
Candidate: 3.6.8-1~18.10
Version table:
*** 3.6.8-1~18.10 500

This happened without any intervention from me - just a random error and report
request.
However, this is the result of what is described above and in more details:
1. Attempted to upgrade to 19.04 via software centre and cmd line, always with
this error:
Reading cache
Checking package manager
Cannot upgrade
Your python3 install is corrupted. Please fix the '/usr/bin/python3'
symlink.
Note that python3 is the default 3.6, it was never changed. Symlink was fine.
Followed good and bad advice. Last one was the first comment here;
https://dev1galaxy.org/viewtopic.php?id=649
The result was a messed up python symlink, which overwrote the binary.
Removed, reinstalled and this error just popped up. Technically so far
things work though but i still cannot upgrade.
