In the process of creating symbolic links, stupidly overusing sudo and not understanding things, I have gone ahead and deleted libstdc++.so.6 from: /usr/lib/x86_64-linux-gnu/libstdc++.so.6 which i think was linking to /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.16 which too I deleted (don't ask why...)
So now i can't run most programs (e.g. aptitude, apt-get) as they give the error: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
So how do I get around this problem? Very amateur linux user so please let me know if I can provide any more information.
Thanks guys! I ended up getting the libstdc++.so.6.0.16 file from a friends computer and creating a file libstdc++.so.6 file linked to that. Also had to make sure to change permissions for libstdc++.so.6.0.16 to 644 ( -rw-r--r-- ). Guessing it would have been a similar thing if I had put in the live cd.
