OK, I've made a little wiki page about this issue for distro maintainers (no real new information, but it does have links to patches at the bottom). The patches should cover all affected versions that Ubuntu supports (40.7, 42.8, and 42.9).

I'm the maintainer of Deja Dup. I was recently made aware that Google is removing an oauth workflow that Deja Dup uses, in September. Here's their blog post about it: https://developers.googleblog.com/2022/02/making-oauth-flows- safer.html Here's the upstream bug about switching to a new oauth flow: https://gitlab.gnome.org/World/deja-dup/-/issues/222 I've released version 43.3 with a new oauth workflow. This basically switches us from redirecting the oauth page to a local http://localhost:xxxx/ page being served by deja-dup and instead has the browser launch a custom URI like 'com.googlecontent.xxx:/oauth2redirect?code=yyy', which then launches deja-dup and gives it the correct oauth token. The key differences for packagers is just to note that now deja-dup will register itself as a handler for those weird URI schemes (they are specific to deja-dup, as they include its client ids for the service). I think this deserves a backport to all supported releases. I can whip up a patch for you in a bit, just wanted to get this registered as an issue. To be a bit more specific about what will break: - Existing users that have already granted deja-dup access to Google will continue to work without any issue. - In August, users will see a warning on the oauth screen. - And then in September, any new attempt to connect deja-dup to Google will not work.
