Cannot install programs with apt-get or Software Center

  • 772

If I try sudo apt-get install mc or sudo apt-get install fortune, I get E: Unable to locate package mc or E: Unable to locate package fortune.

Also in Ubuntu Software Center: Use this source is disabled.

Internet works and wget gets from Internet.

apt

    mc and fortune are both in the universe repository. Make sure you have the option to download and install packages from universe enabled.

    Open software-center. Go to Edit menu --> Open software sources and check Universe option.

    software-sources-gtk

    After checking the option, run the following commands to install mc and fortune.

    sudo apt-get update
sudo apt-get install mc fortune

  3. After you install Ubuntu, run:

    sudo apt-get update && sudo apt-get upgrade

    This will update the package lists and upgrade your system.

    However, if you've already done so, you can follow the instructions given by jokerdino.
