I like Mumble, it’s a simple and effective alternative to TeamSpeak.

Take the time to properly understand Linux file ownership and permission. Permission will be the cause of many issues you will encounter in you self-hosting journey on Linux. Make sure you know the basics of chmod (change permission) and chown (change ownership), Linux users and groups. This will save you some head-scratching, but don’t worry, you will learn by doing !

Remember that, if you setup everything right, especially with docker, running as root / with sudo is not required for any of the services you may want to run.
