Привет все, я пытаюсь установить gromacs 5.1.4

Я - новый пользователь в Ubuntu, и я пытаюсь установить gromacs 5.1.4 в ней, но на последних шагах установки я получаю ошибку при упоминании, что сеть недостижима. Я также добавляю код здесь в случае, если он мог бы прибыть удобный.

cmake .. -DGMX_BUILD_OWN_FFTW=ON -DREGRESSIONTEST_DOWNLOAD=ON
