I have managed to reproduce the problem, I'm attaching a test script that attempts to download a file to a location that's not permitted by snapd's strict confinement.
What happens is that the chromium snap is strictly confined, so it can't write files anywhere on the filesystem. In my test I'm setting the downloadPath to $HOME/.local, and the resulting apparmor denial is: juin 12 16:35:24 bribon audit[35815]: AVC apparmor="DENIED" operation="mknod" profile="snap.chromium.chromedriver" name="/home/osomon/.local/linux-5.7.2.tar.xz.crdownload" pid=35815 comm="ThreadPoolForeg" requested_mask="c" denied_mask="c" fsuid=1000 ouid=1000 I'm afraid you will need to update your tests to download files somewhere they can be written (anywhere in your home directory that's not a hidden folder, or under /media or /mnt, for example). ** Attachment added: "download-test.py" https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1881040/+attachment/5383275/+files/download-test.py ** Changed in: chromium-browser (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1881040 Title: [snap] chromedriver does not download where configured Status in chromium-browser package in Ubuntu: Invalid Bug description: I've recently been forced to upgrade to the SNAP based chromium setup. After being required to work through reconfiguring my $HOME, learn of the need to set up $XAUTHORITY I just now discovered that none of my Selenium based download tests work because the SNAP setup insists on downloading to: /home/xxx/snap/chromium/1165/Downloads rather than where the chromederiver download settings have been configured. Is there a way to override this?
