While fixing package dependencies, the terminal application went missing, and now I cannot locate the application. Is there a way to reinstall the terminal application?
Press Ctrl+Alt+F1 (to enter a virtual console), log in with with your account and install the package
gnome-terminal with the command:
sudo apt-get install gnome-terminal
When you type passwords into a text-only virtual console, you don't see anything on the screen. That's normal.
Return to Unity (or whatever other desktop environment you're currently running) by pressing Ctrl+Alt+F7.
The Middle Way
Ubuntu comes with another (simpler) graphical terminal program that you can fall back on!
Press Alt+F2, type
xterm, and press Enter.
Here you can install
sudo apt-get update && sudo apt-get install gnome-terminal
You'll notice my command is a little different from Bruno Pereira's. Having recently performed lots of package management, you may not need to run
sudo apt-get update. (Unless your dependency problem was from
apt-get and you didn't run it with
update before, then you definitely need to.) You can decide.
xterm is very basic in style. As far as I know, there's no GUI way for
xterm to scroll back, save history, change font and font size, or anything like that. The actual shell's capabilities will of course be the same as in any Terminal, since it's still
bash. (Or whatever you set it to be.)
If you have a longer-term problem of any kind with the GNOME Terminal, you can use
xterm, but it is not as friendly and (in some ways) not as sophisticated as GNOME Terminal.
If you continue to have trouble getting GNOME Terminal working but you're able to install software in general, you can install:
You should not use Konsole for this, however, unless you already have KDE installed. Installing it usually pulls in lots of KDE-related packages as dependencies.
