Uninstall python 3.6

Question

Following this guide Testing Deployment Using a Staging Site, I have installed python 3.6 on Ubuntu 16.04 using:

sudo add-apt-repository ppa:fkrull/deadsnakes
sudo apt-get update
sudo apt-get install python3.6

Unfortunately I now want to use the anaconda package manager, and so to avoid a conflict I'd like to remove all traces of my upgrade. How?

Answer 1

Warning: This will break Ubuntu 18.04 and 18.10. These instructions apply to the specific situation described in the question, on Ubuntu 16.04.

Warning: I have tested this solution, but not very thoroughly. Make a backup, and proceed with caution.

1. Remove the repo:

   sudo add-apt-repository --remove ppa:fkrull/deadsnakes
   

2. Refresh apt cache:

   sudo apt-get update
   

3. Remove the package:

   sudo apt-get remove --purge python3.6
   

Answer 2

I followed the instructions above (1:Remove the repo 2:Refresh apt cache 3:Remove the package and found that a lot of my Linux tools and APPS "Disappeared". Not being an expert in identifying and reinstalling each on demand I opted for a full re-install and update. The advise is to make periodic image and backups more like restore points so that you don't have to start from scratch. Make note of your customizations if you are not already documenting the changes to your machine.

Answer 3

I had the same problem, then I make autogeneration of setup.Py file where i could add an interpreter in the optionbox

I dunno if it can help someone
