fatal: bad object xxx

Question

I tried reverting to a previous git commit with:

git revert xxx 

I'm now receiving this error as a response:

fatal: bad object xxx 

What am I doing wrong? How do I fix this?

Answer 1

I don't know the exact reason why that happens. For me, it's because I forget to pull the entire repository to my local. I have 2 or more path, and each path pulls from different branch

/path/branch_a/ -> pulled from branch A /path/branch_b/ -> pulled from branch B 

on branch A, I made a few modification, and commit as usual. I want that commit (for example the commit ID is abcdef123) appears on branch B, so I use

$ cd /path/branch_b/ $ git branch   master   branch_a * branch_b   $ git cherry-pick abcdef123 

This gives me that kind of error. So I need to pull the entire repository before getting that commit
