The code has all long since been ported to python3, but shebangs were still pointing at python (python2). python2 is not installed on ubuntu-archive-toolbox and shouldn't be. Currently we have a cowboyed symlink ~/bin/python -> /usr/bin/python3 to make extra-germinate work, but now that we've moved off of snakefruit we should update all this code to point at python3 directly so we can drop the cowboy symlink.
