I was trying to install viber using .deb package :

dpkg --install viber.deb

and got the following error :

Selecting previously unselected package viber.
(Reading database ... 373332 files and directories currently installed.)
Preparing to unpack viber.deb ...
Unpacking viber (12.0.0.7) ...
dpkg: dependency problems prevent configuration of viber:
 viber depends on libssl1.0.0; however:
  Package libssl1.0.0:amd64 is not installed.

dpkg: error processing package viber (--install):

Errors were encountered while processing:

Since then I haven't been able to do anything using apt. I always get:

sudo apt install viber                   

Reading package lists... Done

viber is already the newest version (12.0.0.7).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 viber : Depends: libssl1.0.0 but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

The problem is, when I try:

apt --fix-broken install

I get:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Correcting dependencies... Done
The following packages will be REMOVED:
  viber
0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded.
1 not fully installed or removed.
After this operation, 346 GB disk space will be freed.
Do you want to continue? [Y/n]

Is it normal that it says my whole disk space is going to be freed? Otherwise what should I do to fix this?

  • Where did you get the package from? – vidarlo Mar 15 '20 at 12:05
  • And which version of Ubuntu do you use? – mook765 Mar 15 '20 at 12:07

    You were right to read your output carefully and avoid destroying your system. Good job! libssl1.0.0 was dropped in favor of a newer version (libssl1.1) after Ubuntu 18.04. Be sure to tell Viber that their package is old and stale. If you have libssl1.1 already installed (most folks do), then try sudo apt install --force-depends /path/to/viber.deb. Alternately, viber seems available as a snap (snap search viber) – user535733 Mar 15 '20 at 12:15
  • " Otherwise what should I do to fix this ?" find a newer version of the software. In other words: find a version intended for the Ubuntu release you use. Never a good idea to install software outside of the timeframe of an LTS. – Rinzwind Mar 15 '20 at 12:54
  • @vidarlo From viber official website – Walid Mar 15 '20 at 14:49
  • @mook765 I use ubuntu 19.04 – Walid Mar 15 '20 at 14:50
  • @user535733 the --force-depends argument doesn't seem to exist it says "Command line option --force-depends is not understood in combination with the other options" – Walid Mar 15 '20 at 14:52
  • Oops, sorry: apt/dpkg confusion. Try: sudo dpkg --install --ignore-depends /path/to/viber.deb The --ignore-depends flag converts fatal errors into mere warnings. There is no guarantee the software will work with the newer libssl, but it's worth a try. – user535733 Mar 15 '20 at 15:27
  • @user535733 Thanks i have installed viber using dpkg --force-all -i viber.deb but i still have a problem with apt, for example i cannot run apt autoremove it still says that I have unmet dependencies, is there a way to fix it ? – Walid Mar 15 '20 at 15:45
  • No. That's the problem with using --force flags. – user535733 Mar 15 '20 at 15:46
  • @user535733 what do you mean ? is there a way to get apt back working because i cannot install anything in this situation, maybe if i could remove viber manually ? – Walid Mar 15 '20 at 16:08
  • Correct - apt was trying to tell you that the viber deb was incompatible with your release of Ubuntu. That's why you needed to --force it. Uninstall the deb, and that will fix your system. Like I said, viber needs to know that their deb is obsolete. And looks like unofficial snaps are available that won't break your system. – user535733 Mar 15 '20 at 16:11

    @Walid 19.04 is End of life, after fixing your problem you should upgrade to a supported release. – mook765 Mar 15 '20 at 16:37
