Error with apturl in Ubuntu

I was attempting to use playdeb/getdeb and it wasn't working. So I went to the terminal to see what was happening. The problem is I have no idea what this actually means or how to fix it. Any help resolving this would be appreciated.

~$ apturl apt:enemy-territoy

I reinstalled apturl to solve it.

sudo apt-get remove apturl apturl-common
sudo apt-get install apturl apturl-common

Hope it helps.

This solved the issue for me:

sudo apt-get install update-manager python3-update-manager

The python module was missing. Seems to be a dependency bug in Ubuntu 18.04
