I suspect this is caused by `udevadm trigger` and `udevadm settle` that snapd invokes, for some snaps, depending on how they are made, when they are removed.
There are multiple other bugs related to various issues (including desktop crashing or minor annoyances) related to udev. I've added a tag to this bug to ease discovery of such bugs for other developers. ** Project changed: snappy => snapd ** Changed in: snapd Status: New => Triaged ** Changed in: snapd Importance: Undecided => High ** Tags added: udev -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to deja-dup in Ubuntu. https://bugs.launchpad.net/bugs/1809729 Title: Removing a snap triggers 'Starting scheduled backup' notification Status in snapd: Triaged Status in deja-dup package in Ubuntu: New Bug description: Removing a snap triggers the 'Starting scheduled backup' notification then (because I don't have the USB stick plugged in) the `Backup Failed: Error creating directory /media/adam/Adam Eveleigh: Permission denied` dialogue box.
