Unable to start OpenCV test "No module named cv2"

[Po-Hsu Lin]

This issue could be reproduced both on SRU systems and Trusty
(In SRU, it would be skipped due to package requirement not met)

If executed manually:
ubuntu@201101-6974:/usr/share/checkbox/scripts$ ./screenshot_validation ../data/images/logo_Ubuntu_stacked_black.png -o /home/ubuntu/Desktop/ok.jpg

If terminates with error message:
Traceback (most recent call last):
  File "./screenshot_validation", line 24, in <module>
    import cv2
ImportError: No module named cv2

We might need to add package python-opencv into package dependency
To let this test case be able to start automatically

This is likely related to many of our dependencies being ‎encoded as recommendations or suggestions. I'll check out if this is the case here and get back to you.

Looking at that I cannot find the dependency anywhere in plainbox-provider-{resource,checkbox}. I suspect this is the side effect of the fact that we never implemented the job meta data extraction that would be exposed to debhelper. I'd love to implement this.

Opencv is supposed to be installed during the preseed process. Here's the merge request that added that to checkbox-satellite, along with the rationale of why it wasn't done as a dependency:

https://code.launchpad.net/~sylvain-pineau/checkbox-satellite/install_python_opencv_desktop/+merge/209888

You can check the preseed (in yantok they're in /srv/enablement/www/preseeds). I see a few (but not all) have this:

in-target apt-get install -y --force-yes python-opencv; \

This should be done for all non-server systems, so if it's not running, it could be that:

- the package wasn't installed. You can try installing it manually and see if it helps; if so, we need to debug why it wasn't installed.
- The package is installed but the module can't be loaded for some reason.

[Po-Hsu Lin (cypressyew)]

OK cool,
For SRU systems, I think it's just the version of checkbox-satellite is not the latest one,
Therefore the following line cannot be found in preseed.
"in-target apt-get install -y --force-yes python-opencv"
I'll make sure everyone here has it updated before the next SRU cycle.

If it wasn't set as a dependency, we will need to install this package manually on those system that was not installed by the satellite, right?

It seems to be a problem with the checkbox-satellite version used in SRU.

I will close this one, but feel free to reopen it if it happens again in the next SRU cycle
