[snap] KeePassXC should auto-connect removable-media

[Ads20000]

Expected Behavior

KeePassXC should recognize my USB stick out-of-the-box.

Current Behavior

KeePassXC had raw-usb connected but that didn't seem to be enough? KeePassXC failed to access my USB stick until I had run snap connect keepassxc:removable-media removable-media. This isn't particularly user-friendly (especially since no software-centre is able to connect interfaces yet, so this can only be done via Terminal).

Possible Solution

KeePassXC should auto-connect to removable-media. KeePassXC can request the auto-connection here. Once requested (and explained why it's needed), people from snappy with vote on the proposal and, if the vote passes, the auto-connection will be put in place and any new snap install of KeePassXC will have removable media like USB sticks working out-of-the-box.

Steps to Reproduce (for bugs)

1. Insert a USB stick to your computer
2. Navigate to /media in your file manager, observe that the USB stick is recognized there
3. snap install keepassxc
4. Click 'Create new database'
5. Navigate to /media
6. Observe that the USB stick isn't there

Context

I'm trying to save passwords to a USB stick which will allow me to have them off my computer and means I'll be able to access them even if my SSD dies for whatever reason.

Take it up with the snap folks, this is the only solution.

https://docs.snapcraft.io/reference/interfaces

Removable media and raw usb have been manual connect since day 1. I don't foresee then changing that anytime soon.

Request not granted. There should be a feature grown in GNOME Software (and hopefully other software centres) at some point that allows for the interfaces to be connected in that, which would help the user experience here :)

[droidmonkey]

I do wish the snap folks build a GUI around the interfaces at some point and adding it to the settings for the OS. That would go a long way to making this more discoverable and user friendly. Another good option would be to have a system like Android where the app asks the user to grant it permission (this is actually done at the core snap level) and if granted it would connect the interface.

Maybe I'll make that suggestion if it hasn't been made already.
