An update for Apache Tmocat recently pushed into bodhi[1] seems to break CA instance spawning in a spectacular way.[2] It seems that the update once again breaks the loading of Java classes during Dogtag server initialization. I gave the package negative karma and I suggest for you to do the same until the issue is resolved. As a workaround you can either disable updates-testing or use: """ dnf downgrade --allowerasing tomcat """ to downgrade tomcat and dependencies to version 8.0.36-2.fc24 which works.
