  • Log files, dmesg, journalctl and systemctl status are good starting points to get clues for where to start troubleshooting problems, then you can hit the man pages or internet. Watch a video about the typical Linux system file structure means and what directories have important config, log, device, or process files and then go look at those files with cat or nano or ls -la.

    You start to become familiar with how things go together and the usual suspects for problems, but also get better at searching the internet or a wiki for troubleshooting your problem.
