Permission denied am I root Ubuntu error

Both assuming that the '\' are and aren't actual enter for new line; When writing:

apt-get install qt4-qmake libqt4-dev build-essential libboost-dev libboost-system-dev \
    libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev \
    libssl-dev libdb++-dev libminiupnpc-dev

in an Ubuntu, I get

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?

Anyone know what this means?

Type sudo before your statement eg. sudo apt-get install ........

This will temporarily give you root (admin) privileges.

Or there is another user using apt or an apt program already running.

IF you are root, something else is running, Update Manager, Aptitude, dpkg.

Happens all the time after first installation's first run. If you are sure you used sudo or logged in as root. Just restart. Plain and simple!
