Linux compilation instructions: Ubuntu readline package name change

[ratherlargerobot]

Hello,

I am working my way through the Linux installation instructions found here:
https://github.com/dciabrin/ngdevkit/blob/master/README-linux.md

It appears that there is no package named "readline-dev" in Ubuntu 20.04 LTS. However, there is a package named "libreadline-dev". I assume this is the one that was intended?

`$ cat /etc/os-release

You're absolutely right!

I just rebuilt the entire devkit with libreadline-dev as you mentioned, and this works on a pristine ubuntu 20.04 container. So I supposed we can close this issue.

Note that for Ubuntu you can also consume pre-built nightly packages available in launchpad.
