I follow various bugs on Red Hat Bugzilla, and I just received a notification from the Fedora Update System that a new package was available for testing that supposedly fixes a bug I was interested in. I wanted to test it, so I tried to follow the instructions.Unfortunately, although the packages are described as having been pushed to updates-testing, I see no evidence that they are actually there yet. It seems somewhat silly to publish a command for testing an update that initially doesn't work, but this is apparently what they are doing on a regular basis!I tried a couple of things:Commented out mirrorlist and uncommented base-url in /etc/yum.repos.d/fedora-updates-testing.repo to make it use (what I believe to be) the master public download siteyum clean allbut these made no difference to the outcome - still no new packages available, according to yum.Details: It's mesa-libGL (and the other mesa packages) for Fedora 14.
Why are updates pushed to Fedora's updates-testing repos initially invisible?
fedora;yum
By default, you can use:yum clean expire-cacheyum repolist -v updates-testing...which will show you both the last time that Fedora updated (in the metalink/updated row) and the last time you updated (in the repo-updated row). As a quick check you can also just run yum repolist on it's own, and any rows that start with a '*' do not have the latest metadata locally.AIUI Fedora post the messages about packages being pushed as they are approved ... but it can still be a non-trivial amount of time after that before they are in the Fedora repo. (and longer for your local mirror to sync.)
