Built Mapcrafter packages are now available for Ubuntu Wily (15.10).
You can set up the Mapcrafter package repository on your Ubuntu by running the following commands:
echo "deb http://packages.mapcrafter.org/ubuntu $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/mapcrafter.list
sudo wget -O /etc/apt/trusted.gpg.d/mapcrafter.gpg http://packages.mapcrafter.org/ubuntu/keyring.gpg
The commands above add the Mapcrafter Debian package repository to your package manager and import the public key which was used to sign the packages. Then you can run
sudo apt-get update and
sudo apt-get install mapcrafter to install Mapcrafter.
