I just realised that the terminal that appears when I type Ctrl+Alt+T is xTerm and not the usual purple terminal that I get. Also, both the Terminal and Software Center have disappeared from my dash. Neither can be found when searching for Terminal or Software Center by name. They have just disappeared. This has only happened in the last few minutes and I can't recall exactly when they disappeared. What happened?

  • @DevRobot Sorry, I forgot to mention that I was installing Virtual Box 5.

  • @DevRobot VirtualB5 from their website, for 14.04, which leads to a page in software centre (Not the one that first appears when seaching for vitrual box through software centre)

  • You probably mean "from the .deb package" Dec 14, 2015 at 16:06
  • VirtualB5 or Virtual Box 5?

The purple terminal is gnome-terminal, you can call it from xterm. If it was uninstalled for whatever reason, install it again from within xterm:

sudo apt-get install gnome-terminal

For the Software Center (package software-center) do the same:

sudo apt-get install software-center

    I'm pretty sure the package name is software-center, but I can't verify it right now.

    Yes, it's software-center. I edited the answer.

  • Why you presume it was uninstalled?

I had the same problem when installing Virtual Box. The error was, that I was loading the wrong package, 32-bit instead of 64-bit. After the "installation" the terminal and the software center disappeared. I got back the software-center by

sudo apt-get install software-center
