Hi, I noticed that there don't appear to be any tests for the following OSs:

• Ubuntu 18
• Ubuntu 20
• Ubuntu 22
• RHEL 8
• Amazon Linux (2018)
• Amazon Linux 2

In addition, although there are tests for the following OSs, they appear to be either outdated or wrong:

• RHEL 7

I am hoping to fix these myself but, before I do so, I thought I'd open this issue first -- this will be my first time contributing to this repo, so please feel free to let me know if you have any tips, suggestions, etc. 🙂
