Public bug reported: Upgrade from Ubuntu 16.04 to 16.10 gave this error. Somewhere along installation I got the error message that /var/www/html was not accessible. I have modified that folder contents for a webpage and for some reason the owner was root, not www-data, so maybe that did it. But as far as I know /var/www is a generic folder people put their website data in. Not sure why apache2 got so hung-up over it and spat out errors 3 times with the final one of:
"Errors were encountered while processing: apache2 Exception during pm.DoInstall(): E:Sub-process /usr/bin/dpkg returned an error code(1), E:Sub-process /usr/bin/dpkg returned an error code(1)" Then a message popped up saying upgade failed, and will try running dpkg --configure -a Then the upgrade quit without completing. Does anyone know what the final operaiions are to finish installation? is it just apt-get clean then reboot? I tried dpkg --configure -a and didn't get anything.
