Public bug reported:
I'm working through the pretty awesome snapcraft documentation and found what
seems to be a bug:
https://developer.ubuntu.com/en/snappy/build-apps/your-first-snap/
Note, this is a documentation issue, I just wasn't sure where to file
that. It may also be a snapcraft issue, in that 'snapcraft stage'
doesn't seem to work as described in the walk-through.
In the section called "Adding an Ubuntu dependency to a part" after we
add the first part (the go webserver stuff) the instructions say to add
the stage-package: directive and add fswebcam as an item to the
snapcraft.yaml file.
Then it says:
Now let's stage our recipe again (and force it to go through the lifecycle).
$ snapcraft stage
On my Xenial system, this fails to add the fswebcam package. When I run
that command, (Note I have followed the instructions exactly to this
point), I get the following output:
$ snapcraft stage
Skipping pull cam (already ran)
Skipping build cam (already ran)
Skipping stage cam (already ran)
And there is no new addition to the ./stage directory. The walk-through
says I should see several new dirs under ./stage.
I figured out finally that this worked if I did a 'snapcraft clean' to
remove all the staged stuff, and THEN run snapcraft stage, which did
pull the go webserver from github and the fswebcam package from the
repos.
So it's a minor hiccup in the walk-though that can lead to some
confusion when the example does not work as described.
