fglrx failed to upgrade

[Shash]

I was running apt-get update && apt-get upgrade && apt-get dist-upgrade on a friend's ubuntu system (Trusty). The system had not been updated in a long time, so the list of packages to be downloaded was huge (~500MB for updates and ~300MB for upgrades) and due to a slow internet connection, I had left it overnight to download. The updates were over by the time I slept, the upgrades had been downloaded by the time I woke up.

When I woke up, the setup was stuck on various fglrx configuration files on the system which it determined had been changed, and wanted to know whether to keep the original files or update with new ones. I chose to keep the original files. Mid-way through the installation, apport popped up saying an error had occured. The script in the terminal went on running, but once I clicked on "Report Problem..." on the apport window, the script displayed an error regarding fglrx (but continued running till the end, after which it said "errors were encountered while processing: fglrx" and then stopped).
