After latest packages upgrade on my Arch Linux workstation – Viber stopped working.
Found a few solutions, but the only one really solved the issue.
The errors during Viber start looks like next:
[simterm]
$ viber Qt WebEngine ICU data not found at /opt/viber/resources. Trying parent directory... Qt WebEngine resources not found at /opt/viber/resources. Trying parent directory... Qt WebEngine ICU data not found at /opt/viber/resources. Trying parent directory... Qt WebEngine resources not found at /opt/viber/resources. Trying parent directory... qml: type="" qml: type="" qt.network.ssl: QSslSocket: cannot resolve SSLv3_client_method qt.network.ssl: QSslSocket: cannot resolve SSLv3_server_method
[/simterm]
And its window:

Solution #1 (didn’t work)
My first suggestion was that something happened with the Qt WebEngine package itself.
Check if it is present in a system at all:
[simterm]
$ pacman -Ql qt5-webengine|grep resources error: package 'qt5-webengine' was not found
[/simterm]
Install it:
[simterm]
$ sudo pacman -S qt5-webengine
[/simterm]
Run Viber again – no, the same errors.
Re-installing Viber’s package (from AUR) also didn’t work.
Well – have to go and google for real ideas then…
Solution #2 (didn’t work)
Found the Reddit discussion here>>> and another solution in comments here>>>.
Check you Viber’s home content:
[simterm]
$ ls -l ~/.ViberPC total 184 drwxr-xr-x 8 setevoy setevoy 4096 Feb 18 11:56 38096***26 -rw-r--r-- 1 setevoy setevoy 36864 Feb 18 11:56 config.db -rw-r--r-- 1 setevoy setevoy 32768 Feb 18 12:02 config.db-shm -rw-r--r-- 1 setevoy setevoy 98912 Feb 18 12:02 config.db-wal drwxr-xr-x 3 setevoy setevoy 4096 May 23 2018 data drwxr-xr-x 2 setevoy setevoy 4096 May 23 2018 WebLocalStorage
[/simterm]
Move it (do NOT delete!) to backups:
[simterm]
$ mv ~/.ViberPC Backups/
[/simterm]
Run Viber:
Nope – window still displayed partially only.
Restore directory from backup:
[simterm]
$ rm -rf ~/.ViberPC $ cp -r Backups/.ViberPC/ .
[/simterm]
Solution #3 (It works!)
And the final solution found in the AUR’s comments which really worked was to remove the ~/.cache/qtshadercache/ directory:
[simterm]
$ ls -l ~/.cache/qtshadercache/ total 496 -rw-r--r-- 1 setevoy setevoy 6557 Feb 11 14:51 0ae8e51494a69e9723be7ea3412d736939d049d6 ... -rw-r--r-- 1 setevoy setevoy 15557 Feb 6 11:51 d9bb34941b5563b04e9a9a715902c4e960f692b0 -rw-r--r-- 1 setevoy setevoy 20745 Feb 18 12:07 e24592d8d235339875cae31851ad680a190a7cc6
[/simterm]
Move it to backups:
[simterm]
$ mv ~/.cache/qtshadercache/ ~/Backups/
[/simterm]
Run Viber – and it works now.
