Snap image won't run due to sandbox SUID issue.

[bootsa]

Had problems installing and running Snap image.

Trying to install with snap install graasp-desktop_0.11.3_amd64.snap caused:

error: cannot find signatures with metadata for snap "graasp-desktop_0.11.3_amd64.snap"

a rather cryptic message that means snap refuses to install as it has no verification in the snap store.

Solved by running snap install --dangerous graasp-desktop_0.11.3_amd64.snap

Running graasp-desktop gives error:

The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /snap/graasp-desktop/x1/chrome-sandbox is owned by root and has mode 4755.

Apparently this is some permissions problem that needs to be run before build time. See electron/electron#17972

Think @NunonuN had this issue and managed to resolve it... How did you do it @NunonuN? Set permissions and rebuilt the app?

OS: Linux Mint Cinnamon 19.1 Tessa

I have also run into this problem when installing the Snap image. Even by forcing it there were some issues remaining. Would be great to hear if @NunonuN was able to resolve it.

@porduna, do you remember if you ran into this issue?

I don't remember, but I remember having troubles back in the GA, and that there were multiple ways to install it and some failed. I have just tested the snap version and run into the same issue with both 0.5.0 (the one used in the GA) and 0.11.3.

However, using the *.AppImage as in:

$ chmod +x graasp-desktop-0.11.3-x86_64.AppImage
$ ./graasp-desktop-0.11.3-x86_64.AppImage

works, without any need of root/sudo permissions for anything, which is always a good thing.
