Broken python dependencies after trying to re-install

  • 772

I had several installations of python on my ubuntu 18.04 system and tried to uninstall all necessary ones and just properly reinstall python3.6

So i deleted all folders that were listed under whereis python, probably that was a bad idea.

Now if I run sudo apt-get install python3.6 it returns

I then tried to update the minimal package with sudo apt-get install -f --reinstall python3.6-minimal but that returns

I'm not really an experienced linux user, so I'm quite stuck here. Does someone have an idea how I can fix my python installation?

    dpkg: error processing package python3.6-minimal (--configure):
    dpkg: error processing package python3.6 (--configure):
    dpkg: error processing package python3.6-dev (--configure):

    You have 3 dpkg package error to need reconfigure, one thing to do that follow

    sudo dpkg --configure -a

    i see you have 4 package not upgraded

    Make sure all package had been updated and upgraded, run

    sudo apt-get update && sudo apt-get upgrade && sudo apt-get autoremove

    if the output log said 

    Errors were encountered while processing:  
python3.6-minimal  
python-minimal  
python3.6  
python3.6-dev

    try to type sudo apt-get install --fix-broken

    if you still have error encountered while processing that package, try to purge and remove all python and reinstall it again, follow

    sudo apt-get purge python* && sudo apt-get autoclean && sudo apt-get install python*

    Hope this helps.
