Just so that everyone knows:

Dont download patched apks from the internet. Instead, install the patcher from github and a vanilla youtube APK to patch it yourself.

There are no official sites providing revanced APKs and the unofficial sited may contain unwanted software.

For me nextcloud was the biggest gamechanger. A raspberry pi and a SSD and suddenly I didn’t have to store anything at Google drive anymore. And it’s really beginner friendly, especially when using NextcloudPi
