I occasionally deleted my /lib/libc.so.6.
By using LD_PRELOAD I successfully made a link of my /lib/libc-2.12.1.so file in my home folder and now most of the command works (cp, ln, etc...). But I still can not make a new link in /lib/ because sudo still doesn't work
sudo: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory
Anyone can help me out?
