Trying to create a snap for Viber

simos · May 24, 2018, 9:08pm

Viber is current distributed as a closed-source .deb package for Ubuntu.

Here is my (UPDATED: second) attempt to repackage it as a snap package.

name: viber-unofficial
version: '0.1'
summary: Free and secure calls and messages to anyone, anywhere
description: | 
  Authentic conversations, the way you like them
  Deepen your relationships with Viber’s wide range 
  of communication features.
  This is an unofficial snap package for Viber based on viber.deb

I am building now on Ubuntu 16.04 (in a LXD container, container image: ubuntu:16.04). Here is the output,

The execstacks are going to be cleared for the following files:
- /home/ubuntu/viber/prime/opt/viber/lib/libQt5WebEngineCore.so.5
To disable this behavior set `build-attributes: [keep-execstack]` for the part.

Snapped viber-unofficial_0.1_amd64.snap

When trying to run Viber, I get errors about missing libraries. It needs some additional tries to figure out the full list of missing libraries, so that I can add them to the staged package list in snapcraft.yaml.

Update: The following are the old error messages when trying to build the snap on 18.04. Still, do not know what I would get that issue but since snapcraft can create packages on 16.04, I am using that one.

Here is the error message when trying to build in a Ubuntu 18.04 LXD container (ubuntu:18.04 container image).

'libc6' is required inside the snap for this part to work properly.
Add it as a `stage-packages` entry for this part.

Ubuntu 18.04 comes with GLIBC 2.27. The message says that the core image has GLIBC 2.23. The required versions of GLIBC as shown in the messages are 2.27 and also 2.25.

Awesome! I’d be inclined to build in a 16.04 LXD container. It builds and installs here, but complains that it’s missing libxss (and maybe others, I didn’t go any further).

janl · November 2, 2018, 1:39pm

It appears that you can include “libc6” in the stage-packages list to fix this?

lucyllewy · November 2, 2018, 2:01pm

Including libc yourself should be avoided at all costs. It will lead you down a deep hole that is dangerous and scary and there are no white rabbits to follow. Wonderland, that is not.

janl · November 2, 2018, 3:39pm

I am in a twisty maze of rabbit-holes all alike.

So basicaly I need a 16.03 VM to make packages?

simos · November 2, 2018, 4:02pm

Currently, snap packages are targeting the Ubuntu 16.04 Core.
You can verify that with snap info core.

Which means that when you want to create a snap of a binary package, you would need to start off with Ubuntu 16.04. You can either create a 16.04 VM, or just use a LXD container with 16.04.
A LXD container is created in 1-2 seconds, a VM takes much more.

At some point, the core will be targetting 18.04 but for now it’s 16.04.

snapcraft has a feature to create this LXD container for you. But since there will be lots of trial&error, you can create the LXD container yourself.

This : /snap/viber-unofficial/x1/opt/viber/Viber: /snap/viber-unofficial/x1/usr/lib/x86_64-linux-gnu/libQt5Core.so.5: version `Qt_5.9' not found (required by /snap/viber-unofficial/x1/opt/viber/lib/libQt5Concurrent.so.5) should mean that Viber requires Qt 5.9. When looking at the package installed “natively” in Ubuntu 16.04 with ldd /opt/viber/Viber I see:

    libQt5Core.so.5 => /opt/viber/lib/libQt5Core.so.5 (0x00007fb41ed9c000)

which seems to show that the app has a LD_LIBRARY_PATH refering to /opt/viber/lib before the standard OS paths. I think we’ll have to recreate that somehow. I’ll need to catch up with you in making the snapcraft file I think is the right one.

janl · November 5, 2018, 1:59pm

Relevant pages:

Native install:

$ patchelf --print-rpath /opt/viber/Viber
$ORIGIN:$ORIGIN/lib

inside the installed snap:

/snap/viber-bootleg/x4/opt/viber $ patchelf --print-rpath ./Viber 
$ORIGIN:$ORIGIN/lib

so the rpath is not edite. Since $ORIGIN denotes the binarys home directory it should be loading the dynamic libraries from the Viber package rather than the system directories:

Native install:

$ ldd /opt/viber/Viber | grep Qt
    libQt5Sql.so.5 => /opt/viber/lib/libQt5Sql.so.5 (0x00007f2ebf175000)
    libQt5Concurrent.so.5 => /opt/viber/lib/libQt5Concurrent.so.5 (0x00007f2ebf16f000)
    libQt5Multimedia.so.5 => /opt/viber/lib/libQt5Multimedia.so.5 (0x00007f2ebf060000)
...

but the paths become:

/snap/viber-unofficial/x1/usr/lib/x86_64-linux-gnu/libQt5Gui.so.5

which are the system library directories, not the viber package directories.

I managed to make it work with a few warnings. I added the dependencies of the deb package and the glib launcher to configure XDG. Here is my version.

I am using the following snapcraft.yaml (adapted from https://github.com/uglide/viber-unofficial-snap/blob/master/snapcraft.yaml).
I create it inside a Ubuntu 16.04 system container (hence, does not require to create a VM).

What could be the issue? Can I enable something to see more on what is going on?
As noted above, Viber comes with Qt libraries which should be included first, so that it does not use the system Qt libraries.

Well… In my case the problem definitely went away after adding desktop-launch to the command:. I’ve even dug up an old backup branch and backtracked my steps… But I see you already have that.

Here’s an idea (the only productive one that comes to mind for now…): try using an extension. Wither for gnome or KDE.

apps:
  viber:
  (...)
    extensions: [gnome-3-34]

(not sure about the 3-34 version, but you know… Try now, worry later! )

or

apps:
  viber:
  (...)
    extensions: [kde-neon]

I think there’s a decent chance it will do the trick.

Years later but the situation of viber snaps on the store ain’t any better, I’ve been trying to snap viber, with deb as the source, in core22, but have kinda similar issues concerning libraries. Any help would be appreciated. The yaml:
