GitHub starts to upgrade its runner image "ubuntu-latest" from version "ubuntu-20.04" to version "ubuntu-22.04". It will fail to find and install "gcc-8" package on the new runner image. Change some of the runner images from "ubuntu-latest" to "ubuntu-20.04" in order to install "gcc-8" as a dependency. The first revision of this patch tried to replace "$runs_on_pool" in "ci/*.sh" with a new "$runs_on_os" environment variable based on the "os" field in the matrix strategy. But these "os" fields in matrix strategies are obsolete legacies from commit [1] and commit [2], and are no longer useful. So remove these unused "os" fields. [1]: |
