So I was trying to install Cython on my Debian machine, and in the installation it gave me the error code:

 Sub-process /usr/bin/dpkg returned an error code (1)

Now as the pure blooded professional student that I am, after just waking up, I didnt think more of it, and thought Id look at it better later. However now when trying to install anything, or update, apt-get gives me the following

Errors were encountered while processing:
cython
E: Sub-process /usr/bin/dpkg returned an error code (1)

sudo dpkg --configure -a gives the following

Setting up cython (0.25.2-1) ...

  • I think the relevant part is `ImportError: No module named 'ConfigParser' maybe this comment might help?

  • Does sudo dpkg -C output anything?

  • @StefanM Yes, it did indeed help, I had to change my Python version back to 2.7, then run sudo apt purge cython. Thank you!

To unblock apt, you’ll need to remove the cython package:

sudo apt purge cython

Fixing the cython installation is likely to be a bit more involved (see the question comments).
