~joeldjohnston -- My system was acting like described in this ticket, but it is an AppArmor issue. I had to disable AppArmor entirely in GRUB, disabling it via systemd wasn't enough. After upgrade from 20.04 -> 22.04 -> 24.04, the paths in /etc/apparmor.d/sbin.dhclient don't match the paths installed by apt/dpkg. Several other apparmor definitions are wrong, so you can't just disable a few policies. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/2055012 Title: When I upgraded from 22.04 to 24.04, DNS resolution went wrong.
