Answer 1

First off, here's your question, nicely formatted (surround it in < pre > tags to get this):

kt@rails-ubuntu:~/rails/ledger/releases/20080820144914/.git/hooks$ ls -al
ls: cannot access post-commit: No such file or directory
ls: cannot access update: No such file or directory
ls: cannot access post-update: No such file or directory

Anyway, you need to boot up in single-user mode and run fsck. If you can't reboot right now, just move the directory to /tmp and forget about it.

Answer 2

(a) Looks like you have some kind of filesystem problems; I'd recommend you run fsck and see if it finds anything

(b) Really not a programming-related question, so off-topic here.
