## Problem statement The `check-packages-functionality` jobs ensure packages are installable before they are delivered to GitLab customers. When preparing the release candidates for the 18.10 release, OpenSUSE failures in the `check-packages-functionality` were not detected because the jobs are allowed to fail: - :green_circle: Pipeline: https://dev.gitlab.org/gitlab/omnibus-gitlab/-/pipelines/430669 - :red_circle: `check-packages-functionality pipeline` https://dev.gitlab.org/gitlab/omnibus-gitlab/-/pipelines/430703 The errors were spotted when tagging the final version for 18.10, one day before releasing packages to our customers. ## Set `strategy::mirror` for the `check-packages-functionality` trigger job in the tag pipelines Set `strategy:mirror` in the check-packages-functionality trigger job in the tag pipeline CI configuration. This will allow release tooling to detect and surface these failures during RC validations. ## To do - [x] Set `strategy:mirror` in the check-packages-functionality job in the CI config (omnibus-gitlab): https://gitlab.com/gitlab-org/omnibus-gitlab/-/merge_requests/9238 - [x] Merge backports to the maintained versions * [x] 18.10: https://gitlab.com/gitlab-org/omnibus-gitlab/-/merge_requests/9282 * [x] 18.9: https://gitlab.com/gitlab-org/omnibus-gitlab/-/merge_requests/9283 * [x] 18.8: https://gitlab.com/gitlab-org/omnibus-gitlab/-/merge_requests/9284
