Over twenty five odd years, I have found the path to a general debugging prowess can best be achieved by doing it. I'd recommend taking the list/buying the book, using https://up-for-grabs.net to find bugs on github/bugzilla, etc. and doing the following:

1. set up the dev environment

2. fork/clone the code

3. create a new branch to make changes and tests

4. use the list to try to find the root cause

5. create a pull request if you think you have fixed the bug

And use Rule 0 from GuB-42: Don't panic
