I'm having the same issue. Looking at the nvidia-glx.postrm in /var/lib/dpkg/info shows that it is trying to revert back to the xlibmesa version of the Open GL libraries, however they are currently owned by nvidia-glx-new.
Perhaps the attached patch can fix this - by checking if the files are owned by nvidia-glx? ** Attachment added: "patch that performs a sanity check on each of the nvidia-glx files to ensure that they are owned by nvidia-glx and not nvidia-glx-new" http://launchpadlibrarian.net/9582409/nvidia-glx.postrm.patch -- package nvidia-glx None failed to install/upgrade: subprocess post-removal script returned error exit status 2 https://bugs.launchpad.net/bugs/130208 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
