I am reading the book "Why programs fail" from Andreas Zeller. It has exercises that requires using the Android automation tool (not to be confused with Google's OS). I could download it from the author's website but when I started the android file as described in the user's guide I got the following error:
bash: ./android: /usr/bin/expectk: bad interpreter: No such file or directory
I tried to install expectk:
sudo apt-get install expectk
But I got the error message:
E: Package 'expectk' has no installation candidate.
The question is: How can I install this expectk to make Android work? I am working on Debian 9.
