    What terminal application are you trying to open? What notification appears? Are you able to open another terminal emulator program? – FourOhFour Jun 3 '18 at 17:24

I solve this problem by installing xterm from software, and running /usr/bin/gnome-terminal. This gave me an error I hadn't seen before, which was that my python installation was not as expected. I fixed the python installation and everything works again.

The python issue was that I was trying to use a python version manager, but gnome-terminal was looking for the binary python3 in /usr/bin. I had disabled that binary by renaming it to old_python3. I renamed it again to python3 and everything worked.

    Perhaps complete your answer by adding information about how you fixed the python installation in the event others face the same issue? – Graham Aug 27 '18 at 16:03

  • I am also facing the same problem after installing python 3.7.0. @steel, Could you explain a bit more -- A binary I had moved. Which binary had you moved from which location to which location and also which binary? – testuser Sep 15 '18 at 10:12

    @Johir I added the details to the answer, but it was specifically looking for the python3 binary. – steel Sep 15 '18 at 13:15

It might be possible that terminal is missing from your system for some reason. You can check that by checking out

/bin/gnome-terminal 

You can install it using ubuntu software center. Open the software center and type "terminal" and then install it.
