While upgrading from 11.10 to 12.04 the upgrade stalled because it said xscreensaver needed to be uninstalled. I tried to open a terminal but the system wouldn't respond. So I did a hard boot and now I can't get past the Ubuntu loading screen. When I got to the root screen I get a message:
mountall: /lib/x86_64-linux-gnu/libc.so.6: version 'GLIBC_2.14' not found (required by /lib/libpllibply.so.2
I don't really know what to do from this point on.
