Errors while removing packages

Question

I tried to remove packages using

sudo apt autoremove

But it shows the following error

Reading package lists... Done
Building dependency tree       
Reading state information... Done

 linux-image-extra-4.4.0-128-generic
E: Sub-process /usr/bin/dpkg returned an error code (1)

What is the error?

Answer 1

I believe that the error is exactly as it seems; dpkg was somehow interrupted in the middle of its operations.

The way to fix that would be to run two commands: sudo apt install -f and sudo dpkg --configure -a respectively to fix your problem.
