Upgrade to 12.04 LTS failed, unable to boot
- by stargazergal
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.
