repowerd not having a build powerpc, ppc64el and s390x makes autopkgtests fail

[Timo Jyrinki]

This bug report is inspired by the problem vivid and xenial are seeing when executing ubuntuone-credentials tests. A regression is detected by the autopkgtest infrastructure:

https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-xenial-ci-train-ppa-service-landing-070/xenial/ppc64el/u/ubuntuone-credentials/20160812_085933@/log.gz

This happens for ppc64el and s390x (powerpc does not have test infrastructure). The reason for the failure is a dependence on installing repowerd which does not have builds for these three architectures.

The bug can be freely modified to address the issue at hand in the best way.

Options include at least:
1. Have "stub" functionality in repowerd for these architectures.
2. Have ubuntu-system-settings (is it the only one?) depend on powerd (transitional package to repowerd) only on the four other architectures.

Update: original powerd didn't have these archs either ->
3. If the problem is u-s-s depending on "powerd" transitional package (available on all architectures), switch the dependency to repowerd instead.

It might be that the option 3. I added reveals the real problem and the easiest fix, in ubuntu-system-settings.

u-s-s depends on powerd (>=0.15) | gnome-settings-daemon

Since powerd is missing (and always has been missing) on ppc64el, I would expect the dependency to be fulfilled by gnome-settings-daemon, but, if I understand the log correctly, the log indicates that gnome-setting-daemon couldn't be installed, which is highly suspect, since it exists on that arch, but for some reason is not installable.

The related log part:

It is confirmed now that https://code.launchpad.net/~timo-jyrinki/ubuntu-system-settings/switch_dep_powerd_to_repowerd/+merge/302934 is the fix, vivid green on also ppc64el for ubuntuone-credentials and ubuntu-system-settings-online-accounts https://requests.ci-train.ubuntu.com/static/britney/ticket-1801/landing-012-xenial/excuses.html
