The problem turned out to be a bad DHCP option in my pfSense DHCP server. I did not save the option after I was poking around. I am kind of surprised it became part of the server's configuration.
The bad option took down all my Linux machines. It took down about 12 of them - Debian, Ubuntu, Kubuntu, Mint and Fedora. That ISC dhcp client is so damn fragile. It is scary to think you can take down an entire network because ISC's client is so fragile. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to Kubuntu PPA. https://bugs.launchpad.net/bugs/1963747 Title: network broken after March 4 updates To manage notifications about this bug go to: https://bugs.launchpad.net/kubuntu-ppa/+bug/1963747/+subscriptions -- kubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
