Comment 3 for bug 1274012

To be more clear:
I installed Ubuntu 15.04 final, than I was going to install Guake terminal to it.

apt-get install guake
...
Preparing to unpack .../guake_0.5.0-2_i386.deb ...
Unpacking guake (0.5.0-2) ...
...

update-alternatives: using /usr/bin/guake to provide /usr/bin/x-terminal-emulator (x-terminal-emulator) in auto mode
# ^ this is not expected behaviour.

Usually I install Guake and use it as auxiliary terminal on demand.
In previous versions of Ubuntu after Guake installation my main terminal remains gnome-terminal.
But in 15.04 this changed, so I need to choose gnome-terminal manually.
