I have Ubuntu-Gnome 14.04 (Gnome 3.12.2).

When I try to run gnome-terminal by following command :

$ gnome-terminal
Error constructing proxy for org.gnome.Terminal: /org/gnome/Terminal/Factory0: 
Error calling StartServiceByName for org.gnome.Terminal:
Process /usr/lib/gnome-terminal/gnome-terminal-server exited with status 8
  • Experiencing the same error message on Ubuntu 19.04 / GNOME Terminal 3.34.2, I found this answer worked. – John McFarlane Feb 7 at 17:47

You have to add LANG=en_US.UTF-8 to /etc/default/locale and reboot your system. (Solution from this Arch Linux forum post.)

    This didn't work for me. – Cerin Feb 3 '17 at 15:03
  • Worked for me! It looks like I had LANG=en_US.UTF-8 in my file, but it was commented out. Uncommented it and rebooted, then gnome-terminal started right up. – Malachi Bazar Sep 13 '18 at 16:51
  • 4y since this answer. and the user feedback when this is hit is still the same. – hbogert Feb 25 '19 at 8:40

Here is the list of commands which helps me:

sudo apt install dconf-cli
dconf reset -f /org/gnome/terminal
sudo apt-get remove gnome-terminal
sudo apt-get install gnome-terminal
sudo locale-gen --purge
sudo dpkg-reconfigure locales

As you can see I just reinstall gnome-terminal

You probably messed around with your locales. Either add LANG=en_US.UTF-8 to /etc/locale.conf and reboot or delete that file altogether (sudo rm /etc/locale.conf && sudo locale-gen en_US.UTF-8 && sudo dpkg-reconfigure locales) and reboot.

I had this problem when I created a new Ubuntu 16.04.3 LTS Desktop. The fix was to edit the /etc/default/locale file by adding the following line to the end of the file:


Then reboot and the problem was gone.

This is a winner for me:

/usr/bin/dbus-launch /usr/bin/gnome-terminal &

  • In my case, I was trying to run gnome-terminal from inside a shell created by Node.js... There was nothing wrong with my locale file and this solution executing it with dbus-launch was the one that really solved the problem for me. Thanks! – Rafael Muynarsk May 5 at 19:35

Execute sudo dpkg-reconfigure locales in an alternative terminal emulator and select en_US.UTF-8 UTF-8 , choose it as the default locale. gnome-terminal should work.

Another cause of the problem is that new preferences have been activated at the start of the session, check "Applications at startup" Preferences

I had to combine answers from @TomH and @BarryPye. To get a gnome-terminal window:

LC_ALL=en_US.UTF-8 /usr/bin/dbus-launch gnome-terminal

In my case, the issue was occuring in a VNC session. I fixed it in my ~/.vnc/xstartup by changing the window manager invocation to:

LC_ALL=en_US.UTF-8 /usr/bin/dbus-launch /bin/gnome-session

Then gnome-terminal starts directly from command or the gnome graphical launcher, without the need to extra dbus-launch commands.
