The system has become too slow and Terminal tool does not work.

I deleted Ubuntu Software Center.

How do I download it again?

Luckily, the desktop environment runs on top of another terminal, called a TTY. A TTY is a basic terminal found on the system, which the desktop environment runs on top of. To access TTY1, use the shortcut Ctrl+Alt+F1.

  1. A text-based login screen should appear. Login with your regular username and password. The password will not appear on-screen.
  2. Use apt-get to re-install the terminal:

    1. First call sudo apt-get update to make sure you will install the latest version.
    2. Then sudo apt-get install gnome-terminal to actually install the missing terminal.
    3. The software center can then be installed with sudo apt-get install software-center.
  3. Sign out with logout. You can return to the regular desktop environment with Ctrl+Alt+F7.

    In Ubuntu 18 software-center has been replaced with gnome-software, so use sudo apt install gnome-software for step 2.3 instead. See here: askubuntu.com/questions/1036506/…. Feb 2, 2020 at 9:17

    @GabrielStaples, your solution is the only one that worked for me. It seems 'gnome-software' sessions are not handled properly by the system (closing, reopening, etc). Jul 8 at 9:30
  • Error handling could also be improved on the App. It easily breaks whenever an error occurs with any installed application. Jul 12 at 11:56

To install Ubuntu Software Center - please follow these 3 steps

To fetch the latest package installations:

sudo apt update

To install all current updates:

sudo apt upgrade

To install the software-center again:

sudo apt install software-center
  • @michal rejected your proposal to edit: apt will work for update, upgrade and install. No need to use apt-get instead.

  • @MadMike The editor will not be informed, when you reject and edit, if you wish, you can choose causes harm and add a custom reason, to let them know but unless it is there post or they comment, they will not get the notification. Apt will work but only on 16.04.

  • @MarkKirby thanks for the hint. As for apt: I have just upgraded from 14.04 to 16.04 this weekend and I have used apt on 14.04 for some time successfully.

  • @MadMike You can but you must install apt package first (unless it was added in an update and I don't know), soon apt will completely replace apt-get, it is not a big deal, older version users will be prompted to install apt if it is missing
