Viber does not start after update to 7.0.0.1035

[ockac23]

Hi folks,

Yesterday I noticed, that my desktop version of the Viber application misses some new features and I decided to update the application on my Ubuntu 14.04. 64 bit system.

Old Viber version 6.5.x.x...?
New Viber version after update 7.0.0.1035

I downloaded the viber.deb file and installed it with the command #sudo dpkg -i viber.deb. Installation ran successful.
The Viber icon appears in my start menu now but Viber does not start anymore.

I tried several things. If i try to run:

~ /opt/viber/Viber

the output is as follows:

/opt/viber/Viber: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /opt/viber/Viber)

You could try a full-upgrade.
From man apt:

upgrade
upgrade is used to install available upgrades of all packages currently installed on the system from the sources configured via sources.list(5).
New packages will be installed if required to satisfy dependencies, but existing packages will never be removed.
If an upgrade for a package requires the remove of an installed package the upgrade for this package isn't performed.

full-upgrade
full-upgrade performs the function of upgrade but will remove currently installed packages if this is needed to upgrade the system as a whole.

sudo apt update
sudo apt full-upgrade

[ockac23]

Thanks for the idea, guber2.
But viber still does not start after this.

:~$ sudo apt full-upgrade

The problem seems to be described HERE (https://github.com/CauldronDevelopmentLLC/CAMotics/issues/178) for another package in Linux Mint 17.3 which is based on Ubuntu 14.04.

You need at least libstdc++.so.6.0.20 for GLIBCXX_3.4.20 support.
This library is provided by libstdc++6 v4.9.0.
Since you have v4.8.4 you are one minor version behind.
v4.8.4 provides C++ ABI support only up to GLIBCXX_3.4.19.

I tried the solution offered to use a ppa to install a newer version of gcc.
This was done on a live cd of 14.04.5 where I installed the latest viber.deb then added the repo...

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update
sudo apt install gcc-4.9
sudo apt install libstdc++6


After install it showed I now have GLIBCXX > 3.4.19 ...

ubuntu@ubuntu:~$ strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX_3.4
GLIBCXX_3.4.1
GLIBCXX_3.4.2
GLIBCXX_3.4.3
GLIBCXX_3.4.4
GLIBCXX_3.4.5
GLIBCXX_3.4.6
GLIBCXX_3.4.7
GLIBCXX_3.4.8
GLIBCXX_3.4.9
GLIBCXX_3.4.10
GLIBCXX_3.4.11

GLIBCXX_3.4.22

After using the ppa it would be a good idea to disable and make yourself familiar with ppa-purge if not already.
How to purge a PPA (http://www.webupd8.org/2012/02/how-to-use-launchpad-ppa-add-remove.html)

[ockac23]

Ahh guber2, I tried all the steps above, it does not work. The app does not start.
I don't know why.... Maybe I will wait for another viber update on my ubuntu and till then I will use the app only on my phone.. :-(
Thank you for your efforts.

[again?]

ok.
Just curious.
Was your output from the following showing greater than GLIBCXX_3.4.19 as in my previous post.

strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX_3.4

You could move on to the next LTS, Ubuntu 16.04, a little earlier than you might have normally.

[ockac23]

I have done these steps again today,

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update
sudo apt install gcc-4.9
sudo apt install libstdc++6

and suddenly viber 7.0.0. started this time..... I don't know why yesterday it did not work. Maybe because I have purged the ppa after installing the above packages using the command

sudo add-apt-repository --remove ppa:ubuntu-toolchain-r/test

But that's what I understood from the article, that a ppa can be purged this way to free space without uninstalling the packages?

And regarding your last question, there is no output of the code:

strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXXGLIBCXX_3.4

The cursor just goes to the next line.

[again?]

Ahh sorry, the strings command was a copy and paste error.
Should be

strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX_3.4

As for ppa-purge, that was only meant to be used if for some reason the packages from ppa:ubuntu-toolchain-r/test
caused problems.
ppa-purge disables a PPA and reverts to official packages.
You should also use ppa purge on all third party repositories before you upgrade Ubuntu to a new release.

I still recommend to disable the ppa using software and updates > other software.
If in the future you wish to purge the ppa, you will need to re-enable.

I first thought when the ppa didn't work ...maybe ockac23 went all the way through and ran ppa-purge as well.
Said to myself, "Nah... he wouldn't do that" :p

[ockac23]

Hi guber2,

Here the output from the code, as you asked for it:

$ strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX_3.4
GLIBCXX_3.4
GLIBCXX_3.4.1
GLIBCXX_3.4.2
GLIBCXX_3.4.3
GLIBCXX_3.4.4
GLIBCXX_3.4.5
GLIBCXX_3.4.6
GLIBCXX_3.4.7
GLIBCXX_3.4.8
GLIBCXX_3.4.9
GLIBCXX_3.4.10
GLIBCXX_3.4.11
GLIBCXX_3.4.12
GLIBCXX_3.4.13
GLIBCXX_3.4.14
GLIBCXX_3.4.15
GLIBCXX_3.4.16
GLIBCXX_3.4.17
GLIBCXX_3.4.18
GLIBCXX_3.4.19
GLIBCXX_3.4.20
GLIBCXX_3.4.21
GLIBCXX_3.4.22
GLIBCXX_3.4.23
GLIBCXX_3.4.24

And two additional questions.
1.In software and updates -> other software this ppa:ubuntu-toolchain-r/test source code appears twice. Can I delete one of the entry's? Screenshot attached.
2. Should I disable all ppa's in "other software", when I decide to upgrade Ubuntu to 16.4.lts

Thank you.

[again?]

You can delete multiple entries that you may have from adding the ppa twice.

When you add a ppa it also adds a "Source Code" entry.
The "Source Code" entry can be removed or disabled also if you like.
Only needed if you want to download and inspect the code.

It's always a good idea to run ppa-purge on added ppas before upgrading.
This command will list your enabled ppas in a form to use with ppa purge.

for PPA_FILE in $(ls /etc/apt/sources.list.d/*.list); do cat ${PPA_FILE} | egrep -v '^#|^ *$' | grep "ppa.launchpad.net" | cut -d "/" -f4-5; done
eg for me...

glen@GU17:~$ for PPA_FILE in $(ls /etc/apt/sources.list.d/*.list); do cat ${PPA_FILE} | egrep -v '^#|^ *$' | grep "ppa.launchpad.net" | cut -d "/" -f4-5; done
graphics-drivers/ppa
linvinus/altyo
team-xbmc/ppa
So to purge the xbmc ppa I would use

sudo ppa-purge ppa:team-xbmc/ppa

You should start with a base as close to default as you can which includes removing proprietary gfx drivers.
I prefer not to upgrade but just do fresh installs.
Saves the headache of not knowing if an upgrade is the cause of a problem.

Tips for using ppas:
Always check in synaptic to see what the ppa contains as it may also contain other unwanted upgrades.

Use the edit button to add a comment to reflect what the ppa contains. This becomes the ppa title in "other software".

Thank you very much, guber2!

Another solution that helped me was:

cd /tmp/
wget http://ftp.pl.debian.org/debian/pool/main/g/gcc-4.9/libstdc++6_4.9.2-10_amd64.deb
sudo mkdir /opt/fakeroot
sudo dpkg -x /tmp/libstdc++6_4.9.2-10_amd64.deb /opt/fakeroot/
# run Viber
( LD_LIBRARY_PATH=/opt/fakeroot/usr/lib/x86_64-linux-gnu/ /opt/viber/Viber )

You should also use ppa purge on all third party repositories before you upgrade Ubuntu to a new release.

I still recommend to disable the ppa using software and updates > other software.

So guber2, just to clarify, when upgrading ubuntu to a new release, is it enough to disable the ppa using "software and updates > other software" or I should purge it?

Using ppa-purge is the safest way to go.
It will downgrade third party packages or if there is no version of a third party package
in the official repos, it will remove it.
