Deepin (Debian 9) Snaps Have No Internet Connection

Hey guys!

I just installed Deepin Linux 15.10, it is Debian 9 based and I tried to install some snaps. VSCode works fine. However when I tried to install Snap Store, Postman, Spotify it seems my snaps do not have internet access.

Here is an image (when I try to start Postman):

Here is the log:

Error org.freedesktop.DBus.Error.UnknownInterface: Object does not implement the interface - I guess that’s the error but I can’t solve it, Snap Store says:

Both fail to connect to their severs.

I tried disabling app armor and the result was the same. Hope someone can suggest something.

Bump bump bump bump bump.

I’m getting the same issue here :frowning: … did you found any solution?

Nope, not at all. Sad :confused:

shit … that’s pretty bad ::cry: :sweat:

@tajize or @kmanev073: it is a bit hard to say what is happening given the information you’ve presented. Here are a few things that could help:

  1. Could you provide the output of snap debug sandbox-features? This will test some of the kernel features snaps depend on and report back.

  2. What kernel version are you running? When you say that Deepin is based on Debian 9, does that mean that it uses the kernel binaries published by the Debian project? If Deepin provide their own kernels, there might be some required features disabled.

  3. When you run one of the malfunctioning snap applications, is there any relevant messages output to dmesg?

Note deepin is already doing something very different to the point where no snap that tries to use X works, as I described in another topic.

Wow, still nothing here? I’m having the same issue so fixing to wipe Deepin 15.11 and just go with Debian 10 Buster

or Fedora ;D just kidding… the problem is, what @chipaca already tried to describe is, deepin is using a lot of very specified and partly proprietary window manager combo stuff. They startet Deepin De based on WebKit and HTML5, than switched Qt 5 and everything is really custom. A lot a snaps rely on basic gtk and basic X or Wayland. Thats partly the Problem why Deepin is causing some trouble… I used it myself for like half a year but switched because Fedora was a smarter decision for me.
