I updated F25 to libdb-5.3.28-21.fc25 and while dnf worked fine, gnome-software stopped working and complained about a failure to open rpmdb:Hi folks!
So as you may have read, F26 Beta was held up by a tricky bug which
causes upgrades to hang in some situations:
https://bugzilla.redhat.com/show_bug.cgi?id=1397087
https://bugzilla.redhat.com/show_bug.cgi?id=1394862
There are updates in F24, F25 and F26 at present which we hope should
resolve this bug without causing other problems, but the code in
question is quite sensitive so we want to be as sure as possible that
it's good to go.
It would be great if folks can help test. You should probably only test
if you're confident in the old RPM database recovery trick - 'rm -f
/var/lib/rpm/__db* ; rpm --rebuilddb' - and on systems which aren't
*completely* mission critical.
To test upgrading, please update to the newer libdb on the 'from'
release first (F24 or F25), then run an upgrade *with the updates-
testing repository enabled*:
dnf system-upgrade download --releasever=26 --enablerepo=updates-testing
Or if you want to avoid potential issues with other updates-testing
packages, create a side repository with only the libdb-5.3.28-21.fc26
update: https://bodhi.fedoraproject.org/updates/FEDORA-2017- a4c41ecc27
in it, and enable *that* repository during the upgrade. Please check
that libdb-5.3.28-21.fc26 is listed in the set of packages to be
upgraded before running the upgrade, to ensure your test is valid.
To make sure the patch doesn't cause other problems, please just
install the updated libdb on F24, F25 or F26 and go about your normal
business - maybe test installing, removing and updating more packages
than usual. One of the previous attempts to fix this bug would cause
RPM database corruption when an RPM scriptlet called rpm itself, so
we're trying to catch other issues of this nature.
If you do run into any problems, please report them in the bug reports
and/or in reply to this mail.

The issue disappeared after a reboot. Not sure whether that's expected/wanted.
The upgrade to F26 with libdb-5.3.28-21.fc26 worked fine and the system also seems to work fine.
