Ubuntu – Unable to install Firefox using Ubuntu Software Center

firefoxsoftware-center

When I try to install Firefox through the Ubuntu Software Center, it starts applying changes without downloading the packages first and then I get this message:

Package Operation Failed

The installation or removal of the package failed

Details:

Note : I had tried to install firefox earlier, but it gave an error while downloading, so I downloaded firefox from its official website, and followed instructions I found on https://help.ubuntu.com/community/FirefoxNewVersion/MozillaBuilds
That let me use firefox, but I then thought that using the one from USC would be better, as it would update itself. So I deleted the mozilla build and tried to install again from USC, after which I got the above error. I suspect that my attempt to use the mozilla build might be the cause of the error.

Ok, When I entered 'sudo apt-get install firefox' in the terminal, I got this:

sudo apt-get install firefox

Best Answer

Hit Ctrl+Alt+T to open terimanal and run following commands:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install firefox

If doesn't solve the problem then try following solutions:

  • Reinstall/install the language pack:

    sudo apt-get install --reinstall language-pack-en

  • (Re-)Generate and reconfigure locales:

    sudo locale-gen
sudo dpkg-reconfigure locales

  • The Final solution is to manually set LANG variable by modifying /etc/default/locale.
    Open /etc/default/locale in your favorite editor:

    gksudo gedit /etc/default/locale

    and set the LANG= to en_US.UTF-8 or whatever language you're using, like:

    LANG=en_US.UTF-8

    Changes will take effect after reboot.

After the additional information provided by OP, problem got solved by running:

sudo apt-get clean
sudo apt-get install firefox
