Questions tagged [linux]
Use this tag when your issue involves a Linux laptop/PC or addresses Linux-specific topics on your Android device. 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. Note that questions purely about operating Linux-based OS on Android devices are off-topic.
