Git error: inflate: data stream error (unknown compression method)

Question

I am getting Git error: inflate: data stream error (unknown compression method) fatal: failed to read object <hach>: Invalid argument error when I try do $ git status. How can I fix it?

Answer 1

1. Do a git fsck --full
2. Did it report a corrupted file?
3. If so delete the file, go back to step #1.
4. Do del .git/index
5. Do git reset

Answer 2

I think it happened because maybe your computer or files were corrupted.

First back up your .git folder, then use git fsck --full command to check your file system then delete corrupt files and check it again until your problem disappear
