Bug Description

[ Impact ]

When an identification is in progress, we can't cancel the user verification via Escape key

[ Test case ]

- Start authenticating an user (using a wrong password may make this easier to trigger)
- Hit Escape
- Authentication is cancelled and user can put PIN / password again

[ Regression potential ]

Authentication fails even if it should not, user authentication may lead to user to see the user lists under gdm when not expected.

Hello Marco, or anyone else affected,

Accepted gnome-shell into focal-proposed. The package will build now and be available at in a few hours, and then in the -proposed repository.

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 . 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.
