Why does the password for a zip-file not work?

Question

I've tried to unpack a password-protected zip-file on Ubuntu 14.04. Although I am absolutely sure the password I use is correct the built-in unzip-function gives an "unknown error".

Solution

Install 7zip via your package manager or type

sudo apt-get install p7zip

in your terminal. Then try it again.

In my case, it was p7zip-full
