I am trying to install cerbot on my Ubuntu 16.04.4 server. I was having some trouble with python, so I removed all python versions from the system. I then downloaded the latest 3.8 release from Python.org, and ran

make
make install

However, when I try to run

sudo add-apt-repository ppa:certbot/certbot

I am getting an error telling me that the command cannot be found

sudo: add-apt-repository: command not found

So I then saw an answer to this - which is to install the software-properties-common package.

However doing so gives me this error,

nuser@nserver:~$ sudo apt install software-properties-common

You might want to run 'apt-get -f install' to correct these:

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Any help would be great.

I was able to solve the problem by deploying another instance of Ubuntu 16.04.

I copied the files that I deleted from /usr/bin/py* from the working instance, onto my broken machine.

This got me to a point where I could manually solve my individual errors by updating and removing broken links and packages.

Thank you @BrianTurek and @Guiverc for the help.
