Seen that this morning on a fully updated artful. Shortly after boot, a gnome-software process started consuming 100% CPU and continued doing so for a few hours, after which I killed it. I had not opened the gnome-software GUI, only applied a few updates manually with apt:

gnome-software[6539]: no app for changed timezone@jwendell Note how there’s nothing from gnome-software after 09:58, yet the process continued consuming 100% CPU until around 11:15 (which is when I killed it). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-software in Ubuntu. https://bugs.launchpad.net/bugs/1711178 Title: Gnome Software consumes way too much CPU resources at times Status in gnome-software package in Ubuntu: Confirmed Bug description: I've noticed my Kaby Lake i7 laptop with 16GB RAM become extremely slow at time even when not performing any CPU intensive tasks. I've tried to find out the culprit process and it turned out to be Gnome Software. It was consuming 99% of CPU. I remember having clicking "update all" in Gnome Software some time ago and also "check for updates" in control center's details section some time after that.
