About kernel panic repair – Ask Ubuntu

Because Ubuntu did not start well, when I repaired with fsck with -y, it became "error EXT 3 -sf (device sda ​​1) in station 3 _ delete_inode: failure I 0". After that, "EXT 3 _ reassembly: about forced by the user * will now restart"
"such a file or directory" will be "reboot: error when loading shared libraries: libnih.so.1: can not open the shared object file", the restart of ubuntu has stopped to move.
Upon power up, it will become "libnih.so.1: can not open the shared object file" and will become a panic for the kernel. I want you to tell me how to fix.
