Limitations | unmaintained (see Availability below)
Cuttlefish is unmaintained and therefore has limited availability. Every new Ubuntu release requires someone to whip up a PPA for it, and/or experiment with the deb from a previous PPA.
A 14.04 PPA was made available by the UbuntuHandbook team:
sudo add-apt-repository ppa:ubuntuhandbook1/apps sudo apt update sudo apt install cuttlefish
I have made a test PPA for 14.04, 14.10 and 15.04:
sudo add-apt-repository ppa:kwill/cuttlefish-test sudo apt update sudo apt install cuttlefish
