Не могу запустить контейнер Sentry.io

Решил поставить себе sentry.io. Все делаю по официальной инструкции - вот она

Запускаю установку ./install.sh и получаю такую ошибку

Насколько я понял, в docker контейнере не работает сеть. Пробовал разные решения - ничего не помогает.

Может кто сталкивался - помогите советом
