package doc-base 0.10.6 failed to install/upgrade: subprocess installed post-installation script returned error exit status 10

[Leonard Saers]

I run
 > sudo apt-get upgrade
after adding deb http://archive.ubuntu.com/ubuntu/ utopic main to source list while running Ubuntu 14.0.4

This didn't work so I tried
> apt-get dist-upgrade

After restarting Ubuntu 14.10, I got the error.
