Steps to Reproduce

1. `sudo snap install github-desktop --edge`

2. Open GitHub Desktop. It takes a while the first time.

3. Login

Expected Behavior

The login completes successfully.

Actual Behavior

The login fails with the following message : An AppArmor policy prevents this sender from sending this message to this recipient; type="method_call", sender=":1.291" (uid=1000 pid=22162 comm="/snap/github-desktop/31/opt/GitHubDesktop/desktop " label="snap.github-desktop.github-desktop (enforce)") interface="org.freedesktop.Secret.Service" member="OpenSession" error name="(unset)" requested_reply="0" destination=":1.20" (uid=1000 pid=1732 comm="/usr/bin/gnome-keyring-daemon --daemonize --login " label="unconfined").

Additional Information

I believe it’s because of an undeclared capability in the app. It should be as simple as modifying the package.json file by adding an interface.

Logs

… and I noticed I reported at the wrong place. There’s already snapcrafters/github-desktop#9.

Edit

Solution :

sudo snap connect github-desktop:password-manager-service

With the help of the Snapcraft team, I’ve now been able to publicize the app again on the Snapcraft store now the enclosures are migrated. It is recommended to install the beta channel currently if you are working from a fresh install.

For existing installs the edge channel will remain using the strict enclosure for the moment, and refreshing to the latest version there will ask you to install the beta channel, which is using the classic enclosure and requires a manual upgrade:

@bb441db It works!

sudo snap connect github-desktop:password-manager-service
