We're trying to upgrade some mesa libs in bug 1220658, but this particular ball of tar will require a laundry list of package updates from the precise-updates repo. This repo isn't currently mirrored.

Mirroring the entire repo is fairly easy (modulo disk space), but expect it to cause a lot of other mayhem as it will make new packages available that weren't previously available. Better, I think, would be to figure out the particular packages that you require and mirror those to a custom repo.

Looks there is not too much of mayhem with this repo enabled (see the blocked bug). I don't mind to have the system updated. ;) In the worst case scenario we can revert and only then spend time cherry picking the packages. Last I looked the dependency chain wasn't short. :/

OK, well, mirroring a new repo isn't hard: https://wiki.mozilla.org/ReleaseEngineering/PuppetAgain/Packages and I expect that doing so will determine whether there is enough disk space :) If you need more disk, let me know -- I think we're in a position where adding a few more tens of gigs is just a reboot and some LVM commands on all of the masters.

Hmmm, I'm getting rsync: failed to connect to us.archive.ubuntu.com: Network is unreachable (101) I wonder if we need to whitelist the rsync ports on releng-puppet2.srv.releng.scl3.mozilla.com or something like that...

Indeed - that seems to have been a change. It's not mentioned either way in the network flow tests.
