I ran into this same issue on my personal remix build.  Please stop breaking Anaconda.  Sure, the Fedora 25 GA live media came out a couple of weeks ago but that doesn't mean you get to break it again. :)

and if this isnt a blivet issue please let us know and will file on the correct componet

Just for some background, I did an install from the last working remix build I had... and then did dnf -y update --refresh to get all of the updates.  Here's what got updated (below).  The problem is that nothing is the obvious culprit.

*** Bug 1404388 has been marked as a duplicate of this bug. ***

This is actually/primarily a bug in the dmsetup utility. It was reported and resolved in rawhide (bug 1393692), but the fix wasn't backported to F25 as it seems.

I rolled back to these previous package versions:

device-mapper-1.02.131-5.fc25.x86_64
device-mapper-event-1.02.131-5.fc25.x86_64
device-mapper-event-libs-1.02.131-5.fc25.x86_64
device-mapper-libs-1.02.131-5.fc25.x86_64
lvm2-2.02.161-5.fc25.x86_64
lvm2-libs-2.02.161-5.fc25.x86_64

And I built a new livemedia image with those versions, and anaconda worked again.

Basically I got the previous package versions from koji, added them to a local repo, and then edited the package list in my kickstart to include the desired package versions for the above listed packages (so it'd grab the older versions from my local repo rather than the newer, broken packages from the updates repo).

I see there are some pending newer versions of those packages (lvm2-2.02.167-2.fc25, etc) currently in updates-testing but looking at the changelog, I'm guessing those don't fix this issue.  I haven't tested those so I can't say for sure.

In fact, yes, they should. The change in 167-2 is specifically intended to fix this. Can you try again with https://bodhi.fedoraproject.org/updates/FEDORA-2016-0510ab2764 (167-3) and see if it works, and up-karma the update if so?

The update FEDORA-2016-0510ab2764 (version 167-3) fixes the issue, at least when using blivet-gui under F25

I can confirm that anaconda works agin with the 167-3 packages.

*** Bug 1405286 has been marked as a duplicate of this bug. ***

updated anaconda fixed this issue and can be closed
