This description is highly unclear and even a cursory attempt at replicating this issue finds no Git bug.

Feel free to provide substantially more information.

Please see the bash console log below.
I'm working on host MD1APWHC in a repository that is shared from host md164x2c.
In the top level directory it doesn't appear to be an repository at all (see git status).
If I change into the bin directory, some git commands work as expected but fetch still fails.

@fsylla several random points:

• Does the contents of that ".git" directory really look like it's a Git database?
• Do you have correct permissions on its contents?
• What happens if you export GIT_DIR=//md164x2c/jfw/.git into your shell's environment and retry?

[dscho]

I tried to reproduce the issue by cd //localhost/c$/git-sdk-64/usr/src/build-extra with Git for Windows v2.14.0(2) and then running git status. It works here.

@kostix
export GIT_DIR=//md164x2c/jfw/.git makes the problem disappear!
My permissions are correct and the repository works as expected as long as I use it locally on md164x2c (without the path of the share).

[kostix]

It might mean some weird problem with the Git's logic used to figure out where the repository's Git database resides (that's why I asked for that test).

The idea is that when you force the location of the database, that algorythm is not exersized.

@dscho
The shell script attached requires admin privileges to create a share named repo.
It assumes d: is writable and tries to create a Repository in d:\tst\repo

sharepo.zip

[dscho]

I think that the problem here was the top-level of the UNC directory, and that I managed to fix it in response to #1320. Git for Windows v2.14.3 will come out later today, with the fix, please keep an eye open and test whether this fixes your issue, too.

[fsylla]

Yes, it does. V2.14.3 behaves as expected. Thank you!
