[Bug 1619285] Re: cc_growpart fails on yakkety

Thu Sep 1 20:19:34 UTC 2016

Martin,
I uploaded just the workaround.  As shown in that commit message, the exit values are not reliable.  Long ago I'd added the workaround, so the change here was really just to extend the list of possible output messages to scrape for.

Not great, but will work.

I also added a autopackage test, so something like this will hopefully
be caught next time.

  same output :

  Apparently this only affects yakkety.
