[Bug 1511049] Re: add-apt-repository intermittently fails on krillin
There is another type of failure, seemingly due to the same cause:
+ sudo add-apt-repository --yes ppa:ci-train-ppa-service/stable-phone-overlay

===============================================
We ran this by the launchpad team and based on the analysis that cjwatson carried out, he had this to say:
'The bit where it only lists a subset of PPAs is a bug in add-apt-
repository. It's talking to the Launchpad API by hand to avoid needing
to introduce additional dependencies, but unfortunately it doesn't
implement the collection API properly: it needs to follow links to
subsequent batches until it's found everything. (Notice that it's
shown you 75 entries, which is exactly our current batch size on
production.) I'd suggest raising that with the Foundations team, who
can come to us if they need help fixing it.
I'm not completely sure why it couldn't add the PPA in the first
place, though, and I suspect the underlying error has been obscured by
add-apt-repository somewhere along the line. I compared with appserver
logs for the relevant timestamps (which are just about still
available); there are records of requests from a bit later in that
hour, but add-apt-repository's request didn't hit any appserver as far
as I can tell. I therefore suspect that it was denied by haproxy due
to temporary high load or some transient network problem, and indeed,
add-apt-repository ought to have some back-off-and-retry logic. Again,
that's something the Foundations team would be best-placed to fix.'
We could add that this issue is only visible for us on krillin devices
and that this is an intermittent issue with somewhat higher frequency.
The mako runs with the same command hasn't failed at all this way.
