Puppet broken on deployment-mediawiki07, deployment-imagescaler02, deployment-redis06, deployment-videoscaler01 due to prometheus exporter packages being missing in stretch
Closed, ResolvedPublic


Possibly related to jessie vs. stretch
Mostly it's just the normal package not found error for the nutcracker exporter, but take a look at this one from -redis06 trying to get the redis one:

Error: Execution of '/usr/bin/apt-get -q -y -o DPkg::Options::=--force-confold install prometheus-redis-exporter' returned 100: Reading package lists...

Is something wrong on the side there?

Maybe stretch is pointing to an old version where as Jessie is pointing to the new one?

Nope, it just plain doesn't exist:

Dug into this a bit more with some help from paladox and mutante, it seems the problem is apt-get update failing due to errors relating to including a stretch-wikimedia experimental sources entry, which seems broken on the end

It's due to the experimental component missing from InRelease file in stretch. It seems the folder exists for it but it was never added to that file. It does exist in the jessie one though.

Change 402431 had a related patch set (by Paladox) published:
[operations/puppet@production] aptrepo: Add experimental to stretch (distributions-wikimedia)

Change 402431 abandoned by Paladox:
aptrepo: Add experimental to stretch (distributions-wikimedia)

Change 402432 had a related patch set uploaded (by Paladox; owner: Paladox):
[operations/puppet@production] apt: Do not use experimental on stretch

Patch handles the errors, got some more ones on some of the hosts

Actually the remaining ones appear to be T153468

Change 402432 merged by ArielGlenn:
[operations/puppet@production] apt: Do not use experimental on stretch

Solved by removing 'experimental' from Stretch apt configuration

Can you also remove apt::use_experimental from the Hiera settings for deployment-prep? There's no point for deployment-prep to use "experimental" at this point.

Welp, it's merged, and the hosts in question no longer have errors since the cherry-pick earlier. Can we close?
