GitLab runners having issues

[Bryan Richter]

Hi everyone,

Unfortunately, many CI jobs are failing for similar reasons on a
number of runners. Examples:

1.

Running /usr/local/bin/cabal update --index=2020-12-21T14:48:20Z...
Downloading the latest package list from hackage.haskell.org
Version of <repo>/root.json is less than the previous version
/usr/local/bin/cabal update --index=2020-12-21T14:48:20Z failed
error: cabal update failed

-- https://gitlab.haskell.org/ghc/ghc/-/jobs/1224391


2.

ERROR: Job failed: failed to pull image
"registry.gitlab.com/gitlab-org/gitlab-runner/gitlab-runner-helper:x86_64-v15.0.0"

-- https://gitlab.haskell.org/ghc/ghc/-/jobs/1224641

Moritz, can you look into these?

Could it have something to do with the GitLab emergency upgrade that
happened yesterday? Or were the runners reconfigured in some way?

I don't have administrative access to these runners.

I have created an issue: https://gitlab.haskell.org/ghc/ghc/-/issues/22422
