attempting to add the same unit twice

[Bin Li]

After install the checkbox20 from stable or edge, it will show below error.

$ sudo cdts.test-runner·

Looks the cdts and checkbox20 defined the client-cert-16-04 at the same time.

cdts/10/providers/plainbox-provider-certification-client/bin/canonical-certification-cli:8:unit = com.canonical.certification::client-cert-16-04

    snapcraft.yaml: remove certification-client

    This provider will be in future checkbox core snap releases
    so should be removed from this snap.

So I installed the cdts from 20.40/edge while not latest/edge. And found the plainbox-provider-certification-client was removed. But there are another issue. The test-runner couldn't find checkbox-cli-wrapper.

cdts 0.6dev 58 20.04/edge ce-certification-qa classic

$ sudo cdts.test-runner·
/usr/bin/env: ‘checkbox-cli-wrapper’: No such file or directory

oh and for the record @binli never run checkbox with sudo cdts.test-runner, checkbox snap via the install hook should take care of installing a sudoer rule for the ubuntu user

@sylain,

 Thanks for your reply. And I also try to run without sudo, it's same result.

$ cdts.test-runner
/usr/bin/env: ‘checkbox-cli-wrapper’: No such file or directory

Candidate builds for version 0.6 are now on the beta channels for all tracks of cdts

[Bin Li (binli)]

@Jonathan,

 I installed the cdts from 20.04/beta, it works perfect and the 'checkbox-cli-wrapper' issue is fixed. Thanks a lot!
