# Troubleshooter

## "A start job is running for ..."

 - Resolve:
	 - Show all devices and their IDs:
	
		```
		blkid
		```
	 - Update the `/etc/fstab` accordingly
		 - Check `/dev/` paths
		 - Check `UUID`s
		 - Check everything!
		 - Fix it
	 - Reboot

## Remove unneeded packages

```

## No playback with Amarok

 - Install optional dependency `gst-libav`
 - Configure Phonon
	 - Amarok > Settings > Configure Amarok > Playback > Configure Phonon

## "Not in sudoers file"

	usermod -aG wheel
	```
 - Reboot
