After I dist-upgrade the Kubuntu 14.04 to 16.04, I ran the following command to update the system state.   sudo apt-get update; sudo apt-get upgrade; sudo apt-get autoremove; Then, I got the following error.  dpkg: error processing gcc-doc (--remove):  Package is in a very bad inconsistent state - you should  reinstall it before attempting a removal.  Errors were encountered while processing:   gcc-doc  E: Sub-process /usr/bin/dpkg returned an error code (1) All the following attempt didn't work  sudo dpkg --remove --force-remove-reinstreq gcc-doc  sudo dpkg --configure -a  sudo apt-get clean  sudo apt-get autoclean At the end, I did a brute force way. Find gcc-doc related files in /var/lib/dpkg/info and remove them  find /var/lib/dpkg/info/ -name *gcc-doc* -print | xargs rm Then,  sudo apt-get update; sudo apt-get upgrade;  sudo apt-get install gcc-doc This worked, but it is now by apt-get/dpkg and has some risk. Please use this with your own risk if
