After some good hints from Oliver I did some investigation on this issue. Indeed it looks like the chromium snap is doing the right thing: it first checks if the D-Bus service "org.freedesktop.portal.Desktop" is running (if not, it falls back on calling ListActivatableNames, which is not ideal because this currently gets blocked by AppArmor -- but in my tests the call to NameHasOwner works, so this path is not even taken), and then it checks that the "version" property on the "org.freedesktop.portal.FileChooser" interface is at least 3.
Unfortunately, on my Focal system this version is 2 (version 3 was released just about at the time when Focal was: https://github.com/flatpak/xdg-desktop- portal/commit/00b28db5ca45bcbdfea0ddfff8447a3f8836bfd9), so the portal dialog is not used. -- 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/1851250 Title: [snap] chromium-browser snap cannot upload files outside ~ Status in chromium-browser package in Ubuntu: Invalid Bug description: After upgrading from 19.04 to 19.10, my Chromium package was converted to a snap. After figuring out how to manually reconnect the password manager, and figuring out how to apply CHROMIUM_FLAGS that used to live in /etc/chromium-browser/default, and noticing that GMail is no longer able to play a sound when a call comes in, now I see that I am unable to upload files from anywhere except my home directory! Connecting chromium:removable-media as in https://bugs.launchpad.net/ubuntu/+source/chromium- browser/+bug/1832711 does not help with anything else. Is there some way to let the file upload dialog work on any file my user account has access to? Or run this snap in --classic mode? If not, this seems like a critical limitation, as I need this multiple times a day. Switching to Chrome or Firefox cannot be the only workaround for this, surely?
