Bug#1011355: deja-dup: Deja Dup's Google support will break in September 2022 for versions < 43.3

[Michael Terry]

Package: deja-dup
Version: 42.7-1
Severity: important
X-Debbugs-Cc: mike at mterry.name

Dear Maintainer,

I'm the upstream maintainer of Deja Dup. Google will be removing
a particular oauth workflow that Deja Dup uses in September.

This means that any new authentications for users trying to connect Deja
Dup to their Google account will fail after that date (existing users that
have already authenticated themselves will continue to work).

If possible, updating to 43.3 will fix this. Debian has already updated
the sid version to 43.3. But for older releases like bullseye (which is on
42.7), I recommend a backported patch.

Here's a wiki page for more information about the issue, including
backported patches for older versions like 42.7:
