Whilst trying to update my Raspberry Pi (with Raspbian OS), I get the following error when I type "apt-get update":
E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied)
E: Unable to lock directory /var/lib/apt/lists/
E: Could not open lock fike /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
Is there anything wrong with what I am doing?
