GIT_DISCOVERY_ACROSS_FILESYSTEM not set

Just type git init into your command line and press enter. Then run your command again, you probably were running git remote add origin [your-repository].

That should work, if it doesn't, just let me know.

ran across this page and several like it all talking about the GIT_DISCOVERY_ACROSS_FILESYSTEM not set message. In my case our sys admin had decided that the apache2 directory needed to be on a mounted filesystem in case the disk for the server stopped working and had to get rebuilt. I found this with a simple df command:

-->  UBIk  <--:root@ns1:[/etc]
--PRODUCTION--(16:48:43)--> df -h
Filesystem                           Size  Used Avail Use% Mounted on
<snip>
/dev/mapper/vgraid-lvapache           63G   54M   60G   1% /etc/apache2
<snip>

To fix this I just put the following in the root user's shell (as they are the only ones who need to be looking at etckeeper revisions:

export GIT_DISCOVERY_ACROSS_FILESYSTEM=1

and all was well and good...much joy.

More notes:

Hopefully that will help someone out somewhere... -wc

For complete the accepted answer, Had the same issue. First specified the remote

git remote add origin https://github.com/XXXX/YYY.git

git fetch 

Then get the code

git pull origin master
