Can't access removable media in Snap Linux - No slots option

electron-builder : 21.2.0
electron: 6.0.10

Hello,

To access removable USB media on Linux, plugs and slots needed to be setup with electron-builder.

Here is my configuration:

 "snap": {
      "confinement": "strict", 
      "plugs" : ["default", "removable-media" ],
      "slots" : ["default", "removable-media" ]
    },

As mentioned in electron-builder docs plugs working perfectly.

But looks like there is no option for slots. And removable media can't be accessed without them.

See more info on snap Linux interface management here:

Right now when we access removable media in Snap package we just receive Permission Denied error like this:

@develar whenever you have time, can you please have a look on this?

I'm in the same position as @vasyl-shumskyi.
I'm trying to get MPRIS functionality to work correctly in a Snap which, if I'm understanding things correctly, means that I've got to configure a slot for it.
Any feedback on this issue @develar would be greatly appreciated.

Btw, thanks for all the great work you guys put in!

@jdstrand could you advice something here as snap developer?
maybe there is some workaround for this issue for electron snap publishers.

'slots' support is needed to build graphical electron based snaps for Ubuntu "snappy" core (e.g. kiosk type apps)

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?

I think it still relevant. Can devs confirm?

Well, it turned out not be electron-builder issue. But snapd limitation.

Snapd doesn't allow to auto-connect removable-media plug.

Checkout following threads for references:

• https://forum.snapcraft.io/t/opera-requests-auto-connect-to-removable-media
• https://forum.snapcraft.io/t/process-for-aliases-auto-connections-and-tracks/455

The only way is to add removable-media plug to electon-builder configuration

"plugs" : ["default", "removable-media" ]

and then connect removable-media manually via Terminal

snap connect snap-name:removable-media

It would be really great if snapd developers make auto-connection of removable media possible.
