Comment 3 for bug 1521730

Here's an explicit HOWTO for the .rpm workaround:

# Get the .rpm (don't worry about the i386; it's an architecture-agnostic Python application)
wget ftp://fr2.rpmfind.net/linux/fedora/linux/updates/23/i386/c/comix-4.0.4-9.fc23.noarch.rpm

# Get alien
sudo apt-get install alien

# Convert the package (must do it as root; -k to keep the right version number)
sudo alien -k comix-4.0.4-9.fc23.noarch.rpm

# Install the package
sudo dpkg -i comix_4.0.4-9.fc23_all.deb
