    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

    Did you try ctrl+alt+t? – Josef Klimuk Jun 6 '18 at 16:22

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


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