I'm trying to upgrade and while doing so, I get the following:

devteam@hephaestusx:~/Projects$ sudo apt-get upgrade

You might want to run 'apt-get -f install' to correct these.

The following packages have unmet dependencies:

 libboost-python-dev : Depends: libboost-python1.46-dev but it is not installed

E: Unmet dependencies. Try using -f.

devteam@hephaestusx:~/Projects$ apt-get -f install

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?
