Adam Conrad, on behalf of the Ubuntu Release Team, has spun up a set of images for everyone with serial 20171015.
Those images are not final images (ISO volid and base-files are still
not set to their final values), intentionally, as we had some hiccups
with langpack uploads that are landing just now.
That said, we need as much testing as possible, bugs reported (and, if
you can, fixed), so we can turn around and have slightly more final
images produced on Monday morning. If we get no testing, we get no
fixing, so no time like the present to go bug-hunting.
(addendum: I was posting this on fridge.ubuntu.com, and thought it could be put here (community.ubu…) too… possibly didn’t fit thread so sorry - but why this ended up here)
