Ubuntu: Error: When I try to install any package


I am using Ubuntu 12.10. I am in great trouble when I tried to install firefox browser. However firefox installation is broken on my system. After this when I go to UBUNTU SOFTWARE CENTER it showing me this message every time and fail to install any other package.


Item cannot be installed or removed until the package catalog is repaired.

When I try to install anything from terminal I always get this below message:

Error1 :

The following packages have unmet dependencies: firefox-globalmenu : Depends: firefox (= 19.0~b5+build1-0ubuntu0.12.04.1~mfn1)

Please tell how I can repair it. Looking for your guidance.


        yes I just seen it and tried this  command: 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?

Try running sudo apt-get install -f in the terminal. This attempts to correct a system with broken dependencies in place.


You need to run uninstall acroread 9.5.1-1precise1 from your system.That is probably creating problems.

Simply try uninstalling acroread using sudo apt-get remove acroread After that, try installing firefox again. In my opinion it should go through after that.


Force dpkg to overwrite files:

sudo dpkg --force-overwrite -i /var/cache/apt/archives/firefox_19.0~b6+build1-0ubuntu0.12.04.1~mfn1_i386.deb  

Then, run this command to fix remaining unconfigured packages:

sudo apt-get -f install  

Anyways, as someone else stated, the culprit here is probably the acroread package. If you continue to see these messages, just uninstall acroread from your system.
