It happens only for wayland. Just tried out again with the tester account. Attached is the output of gio and journalctl for that account. As you can see gio reports two SSD, a HDD, and a DVD but not other mount.

When I boot my system I have to wait at least 10 to 15 seconds for the application icons to load on dock. Meanwhile everything else seems to be working properly. I didn't experience this behavior in Ubuntu 18.04. Also the dock doesn't trigger when I move my cursor to the left of the screen. (I have set the docker to Auto-Hide mode and it's position is on the left of my screen). --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2016-08-03 (1359 days ago) InstallationMedia: Ubuntu 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) Package: gnome-shell-extension-ubuntu-dock 67ubuntu20.04.5 PackageArchitecture: all ProcVersionSignature: Ubuntu 5.4.0-26.30-generic 5.4.30 Tags: focal third-party-packages wayland-session Uname: Linux 5.4.0-26-generic x86_64 UpgradeStatus: Upgraded to focal on 2020-04-23 (0 days ago) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo wireshark _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/1874578/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
