[yocto] Some trivial question about git update-ref refs/heads/rocko ...

[Zoran Stojsavljevic]

I am trying to upgrade my poky distro with current HEAD:
65d23bd7986615fdfb0f1717b615534a2a14ab80

It is ~ one month old.

And to the latest HEAD:370483fce1c2429c81b19dcf8a36394dc3fc3d92
http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=370483fce1c2429c81b19dcf8a36394dc3fc3d92

The transcript what I do is below:
[user at localhost poky]$ pwd
/home/user/YOCTO/oe_core_embedded/poky
[user at localhost poky]$ git update-ref refs/heads/rocko
370483fce1c2429c81b19dcf8a36394dc3fc3d92
fatal: update_ref failed for ref 'refs/heads/rocko': cannot update ref
'refs/heads/rocko': trying to write ref 'refs/heads/rocko' with nonexistent
object 370483fce1c2429c81b19dcf8a36394dc3fc3d92
[user at localhost poky]$ git update-ref refs/heads/rocko HEAD
370483fce1c2429c81b19dcf8a36394dc3fc3d92
fatal: update_ref failed for ref 'refs/heads/rocko': cannot lock ref
'refs/heads/rocko': is at 65d23bd7986615fdfb0f1717b615534a2a14ab80 but
expected 370483fce1c2429c81b19dcf8a36394dc3fc3d92
[user at localhost poky]$

What I am doing wrong?!

Thank you,
Zoran
