I agree @cpbl -- there are almost certainly better options available. Maciej Borzecki detailed a good proposal at https://github.com/snapcore/snapd/pull/7731#issuecomment-585721100 (with some follow-on thoughts added by jdstrand at https://github.com/snapcore/snapd/pull/7731#pullrequestreview-362900171), but at this point it's up to someone to implement it.
I just did the easy/lazy small Zoom PR, since I'm just an internet rando without time at the moment to develop the real fix. Unless something dramatically changes here in the next couple of weeks, I think anyone wanting a simple way to get the old xdg behavior on 20.04 is going to forced to: 1) Use Google-supplied binary Chrome or 2) Switch distros -- 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/1776873 Title: Whitelisted allowedURLschemes breaks some desktop apps Status in snapd: Triaged Status in chromium-browser package in Ubuntu: Confirmed Bug description: https://github.com/snapcore/snapd/blob/7952972d4897e085030b288e44dc98b824f6723a/userd/launcher.go#L55 snapd has a hard-coded list of allowed URL schemes. Currently that is limited to "http", "https", "mailto", "snap". We have a number of applications in the store which are trying to use protocol handlers outside this scope and break when that's not possible. e.g. Telegram Desktop: tg:/ Github Desktop: git:/ IRCCloud Desktop: irc:/ These are the ones I know of, others may also be affected. Can we please at least expand the list to those that we know of, and perhaps research other popular protocol handlers? Ideally we wouldn't have a whitelist, because this delays our ability to land new applications with as-yet unknown url schemes.
