В mystic curl ошибка on Ubuntu

I do have в mystic ошибка:

CMake Error : downloading '' failed

    status_code: 1
    status_string: "Unsupported protocol"
    log: Protocol "https" not supported or disabled in libcurl

  Closing connection -1

upgrading said I had the newest версия of curl, and в recently installed cmake 3.2. What else shall I check? (reinstalling curls эксперт suggested in http://devendraverma.com/install-curl-on-ubuntu-14-04/ did not help.)
