Questions tagged [linux]
Use this tag when your issue involves a Linux laptop/PC, or addresses Linux specific topics of your Android device. (Note that running Linux distros on Android is off-topic.) In the latter case, consider if other tags like e.g. 'command-line' or 'shell' might be better fitting. See the full tag wiki for additional details and hints.
