Terminal Error Message: E: Could not open lock file /var/lib/dkpg/lock - open (Permission denied)

[telesismedia]

After entering the following two command-line entires:

sudo dpkg --configure -a

apt-get -f install

The terminal returns with these messages:

E: Could not open lock file /var/lib/dkpg/lock - open (Permission denied)

E: Unable to lock the administration directory (/var/lib/dkpg/) , are you root?

This problem started after visiting:

https://help.ubuntu.com/community/Medibuntu#Reporting%20Bugs

I was attempting to add this repository along with its packages to handle multi-media codec installations!

I need a solution to this problem!

Thanks,

Thanks for your report.

The second command should be:
sudo apt-get -f install

This will likely resolve your issue. If so please set the bug's status to Invalid.
Thanks in advance!
