boot-failure

I was trying to upgrade to 12.04 LTS, but the upgrade froze in the process (it was stuck for over 8 hours) and I had to do a hard reboot. Now when I boot up, I get the following:

mountall /lib/x86_64-linux-gnu/libc.so.6 version 'glibc_2.14' not found.

I'm not sure what I need to do from here. Do I need to go back to the previous version? Or can 12.04 still be installed? I don't want to lose any of my files.

I am still new to Linux, so please give detailed step-by-step instructions.

Will final version of 12.04 use the power management changes found in kernel 3.3

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version. In this case, kernel 3.3 has seen some very good power management enhancements that are… >>> More
