I was trying to downgrade my latest gnome-terminal to version 3.6.2 as given in
Upgrade to 15.04: What happened to my gnome-terminal tabs?
But after restart, the terminal won't launch. When I try to install the same version otherwise from X term, it notifies me of the error:
**The following packages have unmet dependencies:
gnome-terminal : Depends: libvte-2.90-9 (>= 1:0.34.9) but it is not installable**
Can someone help?
