Viber executable crashes on Ubuntu 20.10 / 21.04

  • 772

I have been using Viber for Desktop (the official .deb package downloaded from https://download.cdn.viber.com/cdn/desktop/Linux/viber.deb ) for at least 4 normal Ubuntu versions (18.10 through 20.04) with no problem. A few days ago I upgraded from Ubuntu 20.04 to 20.10 and now the /opt/viber/Viber executable crashes on startup with the following message on terminal:

Segmentation fault (core dumped)

System log has the following:

Oct 27 19:04:42 xxx kernel: [ 3782.065767] Viber[25573]: segfault at 0 ip 00007ff5e4804bc5 sp 00007fff2e7dc3b0 error 4 in iHD_drv_video.so[7ff5e46eb000+348000]

A crash dump on system's /var/crash directory is also generated.

I have reinstalled the latest version from Viber's website.

I have deleted the ~/.ViberPC and ~/.cache/Viber Media S.à r.l directories from the home directory, but the problem stays the same.

Any other user having the same problem?

Update

I contacted viber.com. First, they answered by proposing a complete removal and re-install. However, this was something that I have already done. After informing them so, they requested the crash dump, which I sent to them.

Currently Viber for Ubuntu is in version 13.3.1 and has not been updated since July 2020. So, we are stuck to this version until an update is released.

For the time being, the temporary workaround is to retry starting Viber after crash, until it does not crash. It seems that the crash is pretty random, with a chance of 10% of the times Viber starting without a crash. So, I wrote the following Bash function and added it to the end of my ~/.bash_aliases file:

function vib
{
  while ! /usr/bin/pgrep -i Viber ; do
    nohup /opt/viber/Viber >/tmp/vib.out 2>/tmp/vib.err &
    sleep 3
  done
}

To start Viber, I simply type vib into a terminal and wait until it starts.

Update (Oct 2021)

This problem seems to have been solved in Viber version 16.1.0.37:

gnome crash viber 20.10

  1. It seems that segfaults happen with free intel-media-va-driver but not with intel-media-va-driver-non-free for other programs as well: https://bugs.launchpad.net/ubuntu/+source/gthumb/+bug/1903569

    Try to replace the free driver like this:

    apt install intel-media-va-driver-non-free

  2. I have same problem.

    Strange but work for me: run viber with argument --help

    cd /opt/viber
./Viber --help

    And edit shortcut /usr/share/applications/viber.desktop

  3. In /usr/share/applications/viber.desktop I got Exec=/opt/viber/Viber %u I replace it with Exec=/opt/viber/Viber and now it seems to start ok (without a crash)

  4. When installed via snap viber-mtd, the application would crash like this:

    $ /snap/bin/viber-mtd.viber
/bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

    After trying a few things, I eventually discovered that the application launches successfully like this:

    $ /snap/viber-mtd/current/opt/viber/Viber

    Seems to be working fine now when launched this way.
