Git pull permission denied linux?

Question

When I run git pull origin test, I get

fatal: unable to connect to cache daemon: Permission denied

followed by the prompt for the github username and password. The directory is located under my homefolder (~/www/software). Any ideas? If I use sudo, it works, but I don't feel like I should have to use su within my own home folder!

Here is the result of ls -l:

Almost all of the changes are made within the application folder

Answer 1

The problem is that git is unable to connect to its credential cache (Read http://git-scm.com/docs/git-credential-cache for more information).

From documentation:

The cache is accessible over a Unix domain socket, restricted to the current user by filesystem permissions.

So all you need is to check a file permission for this domain socket. Usually it is placed in ~/.git-credential-cache/socket and change them to make it accessible by andrewr user.
