Viber неожиданно прерывается при запуске

Просто установленный Viber на 64-разрядной человечности 14.10, но запуск его из меню или .desktop файл не работал; запуск от терминала или с sudo-правами или не результатами с "Прерванным" сообщением; быстрый выстрел от результатов gdb:

 Starting program: /opt/viber/Viber 
Cannot exec /opt/viber/Viber -c exec /opt/viber/Viber .
Error: No such file or directory
During startup program exited with code 127.

Несмотря на все это, file /opt/viber/Viber результаты в /opt/viber/Viber: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=27413a56e406a81595a30b69d35ba4e3ebfb0760, not stripped

Какова могла быть проблема?
