try the following steps.

1. you shouldn't be a root user

2. chown -R <username> devstack    ex: chown -R stack devstack
   3. chmod 770 devstack
   4. cd devstack
   5. ./clean.sh
   6. ./stack.sh
   

I was having the same error. I resolved by starting from scratch and be extremely careful on the following steps:

1. Create the stack user

   adduser stack

2. Give permissions

   apt-get install sudo -y || yum install -y sudo echo "stack ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers

3. Logout from current user and login back as stack user

4. Install git

   sudo apt-get install git -y || sudo yum install -y git

5. Download devstack

   git clone https://git.openstack.org/openstack-dev/devstack

6. Enter the directory by cd devstack

7. Run ./stack.sh

The point is that if you do one of the above steps (even git clone!) with a user different from stack it will give problems with permissions.

make sure your are not doing it a root user, but a stack user

if the git protocol not working, probably you are behind the proxy, therefore change to https:// should work, instead of change in stackrc the best practice is change the GIT_BASE in local.conf like this

...
GIT_BASE=https://git.openstack.org  or
# use github
GIT_BASE=https://github.com
...

Hope that helps!

If the issue persists after

• running user as non-root (as per devstack)
• changed "sed -i 's/git:/https:/g' stackrc"
• chown -R <--username--> devstack

Try this by u-mounting gvfs as

sudo umount /run/usr/1000/gvfs

Because If you are getting the permission and other details for gvfs as per the following

d?????????? ? ? ? ? ? gvfs then just unmount your gvfs using the following command. Your issue will get resolve after following this process.

umount ~/gvfs(umount /run/user/112/gvfs in my case). GVFS (GNOME Virtual File System) is the virtual file system for the GNOME desktop, which allows users easy access to remote data via SFTP, FTP, WebDAV, SMB, and local data via udev integration so you do not need to afraid while unmounting this.

Permission issue, can you go to /devstack and touch a file to see what happens ? $touch test ? for example? are you logged in correctly ? as kevin from the path above ?
