[Enhancement]: add password-manager-service to the plugs

[V-Gira]

What changes would you like?

There is a password-manager-service interface that could allow the Wire Snap to access the desktop environment's keychain

Any extra information?

Hi @popey , and happy belated birthday!

I work at Wire, and our latest release introduced an issue for some of our Linux users, most relevant the Snap has become unusable.

We started to use the system keychain to store users' authentication data, relying on Electron's safeStorage, and AppArmor policies now prevent users using the Snap package to log in.

I am not familiar with Snaps, a bit of digging makes me believe we would need to add the password-manager-service interface to the list of plugs in the .yaml file.

I would be very grateful if you could help me solve this issue, just pointing me in the right direction would be appreciated, I'm perfectly fine submitting a PR.

Thank you for all you're doing,, Linux support for Wire is not yet in the card unfortunately, but I'll be happy to help in anyway I can to render the Snap usable again.

Don't hesitate to reach out, thanks again!

Unfortunately, I have not been able to build a working Snap following those steps on an Ubuntu VM:

snap download wire

unsquashfs wire_365.snap

• edit the snap.yaml file in ./squashfs-root/meta to add password-manager-service to the plugs

snap pack squashfs-root

snap install ./wire_3.32.3079_amd64.snap --dangerous

The resulting Snap starts properly at that point but suffers from the issue as password-manager-service is not connected

after connecting the interface:

snap connect wire:password-manager-service

The Snap hangs on start up following those steps. I seem to be missing something.

I was apparently mistaken, the above steps worked perfectly on an up to date system (ubuntu and kubuntu). I'll raise a PR
