[yocto] [meta-raspberrypi] Seeing "dd: failed to open '/core-image-minimal-raspberrypi3-20161129134515.rootfs.rpi-sdimg': Permission denied" Errors After Update

[Thomas Thorne]

Obviously I was having some trouble when I created this work area: 

~/work/yocto-rpi/meta-raspberrypi$ git branch -l
  krogoth
* master
  origin/krogoth
  origon/krogoth
  origonkrogoth

So I delete all those and try:

$ git checkout origin/krogoth 
warning: refname 'origin/krogoth' is ambiguous.
Switched to branch 'origin/krogoth'

It is not safe to ignore that warning.  What it means is everything went terribly wrong.  Time to delete and try again.  

~/work/yocto-rpi/meta-raspberrypi$ git checkout -b krogoth --track origin/krogoth 
Branch krogoth set up to track remote branch krogoth from origin.
Switched to a new branch 'krogoth'
thomasthorne at thorne-ul-dt:~/work/yocto-rpi/meta-raspberrypi$ git status 
On branch krogoth
Your branch is up-to-date with 'origin/krogoth'.
nothing to commit, working directory clean

That looks more hopeful.

Success!  Thank you for your help.  Not sure why I did not spot the odd branch name.  

Any ideas why the meta-raspberrypi repository will tab-complete branch names without then correctly linking to the remote branch?  To me there is only one mention of krogoth besides that one I created.

The main things I that the builds are all working again.  I will try and pay more attention when doing the checkout step in the future.
