 Is causing problems installing FGLRX driver, as well as long delay between log in and desktop display. I also get a CLI login prompt that disappears after 20 seconds or so then a graphical login prompt appears I'm assuming this is related

Status changed to 'Confirmed' because the bug affects multiple users.

[kangus (kangus)]

I can confirm this bug, there is quick workaround, simply mv /etc/drirc /etc/drirc.bak2 (/etc/drirc.bak already exists as backup from previous configuration)

google only finds a bunch of bug reports for "failed to install/upgrade: trying to overwrite shared" but no explanation.

Could be an issue of a missing "Replaces"-declaration somewhere. Possibly related to multiarch, too. https://bugs.launchpad.net/ubuntu/+source/icedtea-web/+bug/1471677/comments/3 strongly suggests this.
