Title: Extras-Install Fails In UbuntuMATE 14.10
In running the Extras-Install (that installs the Help and Tutorials, along with additional useful system components), it fails to install the Help & Tutorials, and can't start a terminal session to install the additional system components.
Cause Of Problem:
The extras-install needs (for Gnome variants) the “gnome-terminal” and “file-roller” packages, which are not installed by-default in the ubuntu-MATE variant of Ubuntu.
Install the “gnome-terminal” and “file-roller” packages before running the extras-install of the KeyMusician Keyboard.
Fix Available (in version):
When the ubuntu-MATE distribution becomes better established (and its longevity assured), we will enhance the Extras Installer to handle the differences of ubuntu-MATE.
