I did a clean install of Ubuntu 18.04 a few days ago. I've been using the terminal without any issues.

When I tried opening the terminal today, it failed to launch. I've tried launching it from the applications page as well as using the Alt+Ctrl+T keyboard shortcut.

When running gnome-terminal --verbose though Tilda terminal, get the following error:

# Error constructing proxy for org.gnome.Terminal:/org/gnome/Terminal/Factory0: Error calling StartServiceByName for org.gnome.Terminal: Timeout was reached

I've tried reinstalling the terminal by running sudo apt install --reinstall gnome-terminalbut no luck.

After some further reading, I found out that Chrome remote desktop can cause issues for the gnome-terminal to launch. I uninstalled it using sudo apt remove chrome-remote-desktop. The terminal launched successfully once I rebooted.
