I am trying to compile some source which was written for g++-5. I want to be able to install g++-5 on my Ubuntu 20.04. How can I do this?

I was hoping that sudo apt install g++-5 would work. But it doesn't. Is there some repository I can use to install g++-5 in a painless way?

The g++-5 package is available only for Ubuntu 18.04 LTS.

To install it on 20.04 LTS you can download it and install manually by using commands below:

cd ~/Downloads

Since this is `g++`, you'd also likely need the packages for `g++`, `libstdc++`, etc. (`cpp` is the C pre-processor, IIRC, not C++)
