Just as I get Atlas working on Fedora 26, so they go and release a brand new version of it: version 27 was released on November 14th.
There is a ghastly new look (I suggest changing the default jellyfish wallpaper the moment you first log on!), but there is otherwise not a lot listed as being new in the release notes, apart from an upgrade to the latest release of LibreOffice.
Mostly underwhelming, in other words; but still just about the most functional distro out there (imho, naturally). It remains my desktop of choice, anyway. Unfortunately, I can’t actually upgrade my main desktop to version 27 because when I do, I get told:
Error: Problem: package zfs-dkms-0.7.3-1.fc26.noarch requires /bin/ksh, but none of the providers can be installed - ksh-20120801-35.fc26.x86_64 does not belong to a distupgrade repository - problem with installed package zfs-dkms-0.7.3-1.fc26.noarch
As far as I have been able to tell, this is caused by the ZFS on Linux project not having Fedora 27-compatible repositories ready -and, allegedly, they won’t have one until mid-December. So any Fedora 26 users who have committed to using ZFS for their important data won’t be able to upgrade for a few weeks. Fingers crossed for the December timeline.
My laptop doesn’t use ZFS, though, and was able to upgrade without drama.
I’ve also re-jigged Atlas, so Oracle 12c will run on Fedora 27 without too much fuss (the same need to do a software-only install that plagued version 26 also affects version 27, but the workaround previously described works for the new version of Fedora perfectly well):
