I am doing the same thing as OP after doing a dry run of mender a few months ago.
Can we update Raspberry Pi 3 Model B/B+ Raspbian or mention this somewhere on that guide also?
I have been working all night on this stuff, and I got to the end of it all, and it seems I am having the same experience. I do not know for sure yet, but I am working w/ 1.1
I am starting over…
I guess I just
git clone --no-checkout
git checkout 1.1.x
Thanks for working on all of this, it is pretty late here, so I apologize for my dry lifeless post.
