No way to install canonical-certification-submit on a 12.04 system with checkbox installed

[Jeff Lane ]

Because checkbox-ng is broken on 12.04 (it doesn't run on 12.04.5 and also has issues with emtpy data in submissions anyway), I have to use checkbox-certification-server for testing.

However, when I then try to install canonical-certification-submit, the installation chokes because of conflicts between checkbox-cli an checkbox-ng.

So the only way to get the submit tools onboard is to purge checkbox-cli and checkbox-certification-server packages and then install canonical-certification-submit (which pulls in checkbox-ng).

Here's the apt trace:

Ugh... wrong trace... but the error is exactly the same. Here is another were I recreated this in a VM by installing checkbox-certification-server and then trying to get the submit tool installed:

It's a pure packaging issue where checkbox-ng should break/replace checkbox-cli as per debian policy:
