Can't load any pages at all, nor the settings page, history, etc. Nothing works. All pages fail with "Aw, Snap!". Downgrading to chromium-76.0.3809.132-2.fc29.x86_64 immediately restores everything. Upgrading again breaks everything again. This update is completely broken for me.
Every few minutes I experience a complete system hang (mouse cursor freezes, keyboard input is buffered) and this is logged:
Jun 25 20:44:26 a kernel: i915 0000:00:02.0: Resetting chip for hang on rcs0
It recovers shortly afterwards. Any buffered keystrokes repeat a bazillion times.
Problem 1: cannot install the best update candidate for package fedora-packager-0.6.0.1-3.fc27.noarch - nothing provides python2-offtrac needed by fedora-packager-0.6.0.2-3.fc27.noarch Problem 2: package fedpkg-1.35-1.fc27.noarch requires fedora-packager, but none of the providers can be installed - package fedora-packager-0.6.0.1-3.fc27.noarch requires fedora-cert = 0.6.0.1-3.fc27, but none of the providers can be installed - cannot install both fedora-cert-0.6.0.2-3.fc27.noarch and fedora-cert-0.6.0.1-3.fc27.noarch - cannot install both fedora-cert-0.6.0.1-3.fc27.noarch and fedora-cert-0.6.0.2-3.fc27.noarch - cannot install the best update candidate for package fedpkg-1.35-1.fc27.noarch - cannot install the best update candidate for package fedora-cert-0.6.0.1-3.fc27.noarch - nothing provides python2-offtrac needed by fedora-packager-0.6.0.2-3.fc27.noarch
To be clear about my situation: dnssec-trigger with unbound 1.7.0 fails to resolve any names when using the shipped 1.7.0 configuration which contains auth-zone: config for the root zone. This is directly after a reboot.
After commenting out the auth-zone: config, it works again, even after a reboot.
Broken dependencies on installed urw-base35-nimbus-sans-narrow-fonts-20170801-2.fc27.noarch causes failure to upgrade. You need to obsolete any dropped subpackages per: https://fedoraproject.org/wiki/Packaging:Guidelines#Renaming.2FReplacing_Existing_Packages
