Ошибка запуска ICEM CFD: GLIBCXX_3.4.9 не найден

При попытке запустить ICEMCFD (инструмент построения сетки для моделирования потоков) я получаю сообщение об ошибке и анализирую его с помощью LIBGL_DEBUG=verbose:

После прочтения других потоков я попытался обновить libstdc ++ 6 и

sudo apt-get install libstdc++6

говорит мне, что libstdc ++ 6 уже самая новая версия.

Таким образом, следуя этому совету , я обновил свои библиотеки stdc ++, используя

sudo add-apt-repository ppa:ubuntu-toolchain-r/test 
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

, но я все еще получаю ту же ошибку, когда хочу запустить ICEM.
