Hi,
we’ve encountered the following problem:
```
git clone https://github.com/discourse/discourse.git
cd discourse/
git show 92dc829df56cf5166bdeb0b2463a0b1bcbac8238
fatal: bad object 92dc829df56cf5166bdeb0b2463a0b1bcbac8238
```
As far as we know, this only occurs on git \>= 2.0.0, git 1.9.3 works fine.
Neither fsck, repack or gc helps.
The bad object causes many problems, especially when you’re working with submodules.
It would be really helpful, if someone could fix it.

Can we repro this @sam?

I can repro, but I have no idea how to fix it.

I am not sure there is an error here, this is a standard error message:
```plaintext

I found it an old repo:
```plaintext
→ git show 92dc829df56cf5166bdeb0b2463a0b1bcbac8238 | head
tag latest-release
Tagger: Neil Lalonde
Date: Fri Jan 24 15:21:39 2014 -0500
latest release
```
compare to:
```plaintext
→ git show latest-release | head
tag latest-release
Tagger: Neil Lalonde
Date: Mon Mar 2 18:32:21 2015 -0500
latest release
```
Looks like 92dc… is an orphaned object for an old tag - it would no longer be in the repo on github. It’ll get clobbered when we push a new `latest-release` tag.
After running `git gc`, 92dc… is no longer in my local repo.
@floriandotorg: why did you start using 92dc… ?

@supermathie Thanks for your help.
We don’t use it, git complains about this bad object on `git push` with `--recurse-submodules=on-demand` flag, as well as do many submodule commands.
`git gc` doesn’t remove it on our side.

try: `git fetch --all` to update your tags then `git gc`
Not sure why you would even see it in a fresh repo - it’s not there. Something must be referring to it.

Simplest fix for anything odd like this on dev is to nuke the repo and start from scratch
