apt-get autoremove error

Two things to check.

1) Are you running the command using sudo? You need root privileges to run that command. To get those privileges, use sudo:

sudo apt-get autoremove

2) Is Synaptic or another package manager running?

i used that command but it said something about manually run dpkg --configure -a to correct the problem i typed that command in but it gave me anoother message saying: dpkg: requested operation requires superuser privilege

Try:

sudo dpkg --configure -a

when i did that command this is what I got dpkg: dependency problems prevent configuration of openoffice.org-impress:

ok make sure you do not have any package managers open (synaptic etc) and run:

sudo apt-get clean; sudo apt-get update; sudo apt-get -f install

Notice how ALL the commands have sudo at the beginning. This is because installing and uninstalling packages is an administritive task. If you run the command without sudo, it will be running as at a user level so you will be told you arenot permitted to do this as you are only a user.
You gain elevated priveledges to perform administritive tasks by useing sudo (for command line commands) and gksudo (for running graphical apps), if you put sudo or gksudo at the start of a command and are a membe of the admin group, you can authenticate yourself and you will be allowed to do whatever you like.
