• Based on https://gist.github.com/GAS85/990b46a3a9c2a16c0ece4e48ebce7300
• This totorial is for an older Ubuntu 18.04, for a Ubuntu 20.04 please read here --> https://gist.github.com/GAS85/38eb5954a27d64ae9ac17d01bfe9898c

Requirements

• A self-managed VPS or dedicated server with Ubuntu 18.04 running Apache 2.4.xx.
• A registered domain name with working HTTPS (TLS/SSL). HTTP/2 only works alongside HTTPS because most browsers, including Firefox and Chrome, don’t support HTTP/2 in cleartext (non-TLS) mode.

Step 1: Install Apache2

Redirecting GitHub Pages after a repository move

The problem

You have a repository, call it alice/repo. You would like to transfer it to the user bob, so it will become bob/repo.

However, you make heavy use of the GitHub Pages feature, so that people are often accessing https://alice.github.io/repo/. GitHub will helpfully redirect all of your repository stuff hosted on github.com after the move, but will not redirect the GitHub Pages hosted on github.io.
