sudo add-apt-repository ppa:fkrull/deadsnakes
sudo apt-get update

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?

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

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.

Both Python 2.7 and 3.6 are installed by default in Ubuntu 18. But I wish to use the Anaconda Python with conda package manager. To avoid any conflicts I wish to completely remove the default Python 3.6. Are there any way to do that? Please help.

Don't do that , just don't.
you'll have regrets a lot of it.
And I'm serious.
A lot of things will deleted,but by the way, if you already done that don't worry, there is a solutions.
Just run this code in your terminal

sudo apt install ubuntu-desktop

And if you want you can run this one too

#ubuntu-18.04.1
sudo apt install $[ curl //releases.ubuntu.com/18.04/ubuntu-18.04.1-desktop-amd64.manifest | sed -e 's#\t.*##g' ]

Ubuntu 18.04 requires python 3.6 to function. If you remove python 3.6, you won't be able to log in after a restart. Ubuntu will still have python 3.6minimal, even after uninstalling python 3.6. so you will have to remove both. Once that is done, you'll get an error that looks like this.

You can follow the above steps if you break Ubuntu.
