Colin Watson has proposed merging lp:~cjwatson/launchpad-buildd/chrootwait-retry into lp:launchpad-buildd.
Commit message: Retry "apt-get update" on failure after a short delay, as this occasionally fails due to racing with an archive pulse. Requested reviews: Launchpad code reviewers (launchpad-reviewers) For more details, see: https://code.launchpad.net/~cjwatson/launchpad-buildd/chrootwait-retry/+merge/203029 "apt-get update" fails often enough to be annoying, due to racing with an archive pulse. We generally notice this from the FTBFS failures and retry them manually, but it's a manual step that shouldn't be necessary and it's probably not done very effectively for PPAs. It's really a bug in the archive layout that this is possible in the first place, although a difficult and complex one to fix. However, I think we could work around this quite effectively by just retrying after a short delay. Since the builders point directly at the master systems rather than mirrors, 15 seconds should more than suffice. -- https://code.launchpad.net/~cjwatson/launchpad-buildd/chrootwait-retry/+merge/203029 Your team Launchpad code reviewers is requested to review the proposed merge of lp:~cjwatson/launchpad-buildd/chrootwait-retry into lp:launchpad-buildd.
