Our GHA workflows were using
ubuntu-18.04
in most of the places. This image has just been deprecated (8/8/22) and will be completely unsupported end of 2022.This PR changes all workflows to use
ubuntu-latest
instead (which currently meansubuntu-20.04
as per GHA docs).There is some more information in this blog post by GH. We currently experience a planned brownout from using
ubuntu-18.04
.As an alternative, we could also specify
ubuntu-20.04
orubuntu-22.04
. However, I thoughtubuntu-latest
is a reasonable choice for our use case.
