Why do I get the following error message:

josef@josef-Satellite-L755:~$ apt-get install -f
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
josef@josef-Satellite-L755:~$

Thank you for your help

  • IF you read the message it tells you the problem - "are you root?" . Two most common problems are 1. you are not running the command with sudo or 2. another program is running and accessing the file, package manager for example. – Panther Mar 16 '17 at 20:41

You need to preface your command with sudo and enter your password when prompted.
