git fatal: failed to read object xxx: Invalid argument

Question

I am getting the following error if I pull for fetch from remote

$ git pull
remote: Counting objects: 85, done.
remote: Compressing objects: 100% (37/37), do         


        

Answer 1

Finally I was able to fix this issue. I think issue happened when my computer shutdown due to power cut.

I was able to commit any changes in any of my local branch. This means my pack file is no corrupted but some refs are invalid.

Back up your .git first. Then I use git fsck command

$ git fsck --full
error: inflate: data stream error (unknown compression method)
error: unable to unpack 38fe6f16c7e8246d61150f0bc42629dbb532b5ce header

fatal: loose object 38fe6f16c7e8246d61150f0bc42629dbb532b5ce (stored in .git/objects/38/fe6f16c7e8246d61150f0bc42629dbb532b5ce) is corrupt

I deleted the file .git/objects/38/fe6f16c7e8246d61150f0bc42629dbb532b5ce and continuing these steps until I get following output:

$ git fsck --full

...

Now I removed all three refs (.git/refs/remotes/origin/master, .git/refs/remotes/origin/staging, .git/refs/remotes/origin/development)

Voila! Now I was able to pull and push!
