After I updated the packages on my Ubuntu 14.04LTS, my Ubuntu virtual machine that I was running on parallels wont let me log in. Also it won't work for the guest account.
This is the error-log output: xsessions-error

Also if I run any sudo apt-get commands I get the following error:
apt-get: error while loading shared libraries: libstdc++.so.6: cannot ch file or directory
