I have the same problem on Natty. The root cause seems to be this line: setting up libgl1-mesa-glx (7.10.2-0ubuntu2.1) ... update-alternatives: error: alternative link /usr/lib/xorg/extra-modules is already managed by i386-linux-gnu_gl_conf. dpkg: error processing libgl1-mesa-glx (--configure): subprocess installed post-installation script returned error exit status 2
My guess is that this is because of the Nvidia driver because of the content of /usr/lib/xorg/extra-modules: $ ll /usr/lib/xorg/extra-modules lrwxrwxrwx 1 root root 53 2011-08-08 09:30 /usr/lib/xorg/extra-modules -> /etc/alternatives/x86_64-linux-gnu_xorg_extra_modules/ $ ll /etc/alternatives/x86_64-linux-gnu_xorg_extra_modules/ total 12960 drwxr-xr-x 2 root root 4096 2011-08-08 09:30 ./ drwxr-xr-x 6 root root 4096 2011-08-08 09:30 ../ lrwxrwxrwx 1 root root 16 2011-08-08 09:30 libglx.so -> libglx.so.280.13 -rw-r--r-- 1 root root 6356552 2011-08-01 20:23 libglx.so.280.13 -rw-r--r-- 1 root root 6901792 2011-08-01 20:23 nvidia_drv.so -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/833841 Title: libgl1-mesa-glx alternative link To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/833841/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
