Okay here is a fix when it DOES ask for a yes/no or other. Well, at least when it asks one question and you want to answer it "yes". Do not recommend this for general fix.

Cell code is:

%%bash
cd ~/
./GetComponents --parallel https://bitbucket.org/einsteintoolkit/manifest/raw/ET_2017_06/einsteintoolkit.th << END_INPUT
yes
END_INPUT

bill e.g.

bash fixx
for yes/no
