Hello Michael, or anyone else affected,

Accepted deja-dup into focal-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/deja-dup/40.7-0ubuntu2
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
focal to verification-done-focal. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-focal. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Description changed:

  * Impact
  
  The method Deja-Dup is using to authentificate to google account will
  stop working in september.
  
  * Test case
  
  Configure deja-dup to do backups on a google drive account. After
  confirming the authorization through the web browser it should be
  possible to start the backup.
  
  Check on the webview that the files are correctly added.
  
- Restore some data and unsure that's working.
+ Restore some data and ensure that's working.
  
  * Regression potential
  
  The codepath is used for oauth authentification and integration with the
  system mimetype. Check that the webbrowser auth workflow works as
  expected, testing deb and snap based browsers
  
  ------------------------------------------
  
  Hello! 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.
