That is not a failure. It is the expected behaviour from dpkg and from apt. Users gets to either keep their own settings or to replace them with the default ones from the new fglrx-core package (as the conf files were previously provided by fglrx).
If you want to skip the question, and keep the old files, you can try upgrading using the following command: export DEBIAN_FRONTEND=noninteractive ; apt-get dist-upgrade -y -o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold" --force-yes -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/1511301 Title: Failed to upgrade fglrx from 14.502 to 15.200 on Trusty.
