Jenkins web interface has broken artifact links
latest.iso.shasum link is broken; one has to expand
build-artifacts to then find
tails-build-artifacts.shasum which works. Ideally we'd only get the
build-artifacts, where the real files are, with informative filenames and all.
I wasted quite a lot of time trying to find the SHAAAA (it's required by the release process) first ending up with #16026, then realizing I had access to the Jenkins machine where I found the ISO. Only later did I see the expander...
