Ok, the issue seems gone! I cannot recreate it, and I'm not sure why. First, thank you for the quick reply. When I first read your response, I ran the
`echo "deb http://ddebs.ubuntu.com $(lsb_release -cs) main restricted universe multiverse" | sudo tee -a /etc/apt/sources.list.d/ddebs.list` command, and then realized the CPU wasn't being maximally taxed so I didn't continue and decided to try again later. I then ran the disable and stop commands to get rid of the issue temporarily. I later decided to try to recreate the issue, so I ran the corresponding enable and start commands, and the CPU didn't increase. I then restarted my system a couple times, but have yet to see the high CPU and bad networking issues. I can confirm that the avahi-daemon is indeed running. Running `ps aux | grep avahi` yields, avahi 915 0.0 0.0 18920 3868 ? Ss 23:46 0:00 avahi-daemon: running [tomboy.local] avahi 1035 0.0 0.0 18716 348 ? S 23:46 0:00 avahi-daemon: chroot helper Since my initial post I have performed a couple normal package updates, so perhaps one of them solved the issue? The Kubuntu 18.10 I am on is a new release, so perhaps something was discovered and fixed. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to avahi in Ubuntu. https://bugs.launchpad.net/bugs/1799265 Title: avahi-daemon high cpu, unusable networking Status in avahi package in Ubuntu: Incomplete Bug description: Currently running Kubuntu 18.10, Dell XPS 13 9350 Since updating from Kubuntu 18.04 to 18.10, the avahi-daemon has been consistently hampering network performance and using CPU for long periods of time. When booting machine from off state, avahi-daemon uses an entire CPU at max load for approx 10 minutes. During this time, internet connectivity via wifi is essentially unusable. The wifi connection is good, but it seems that http transactions are cutoff mid-way so no webpage is able to load. When waking from sleep, the avahi-daemon causes similar symptoms, but with less than 1 full cpu usage, and with somewhat less degraded network performance, but still quite unusable. I have never had issues with avahi prior to the 18.10 upgrade, so I am fairly confident the issue is rooted in that change.
