Как обновить Ubuntu 16 LTS до 18 LTS после катастрофического отказа чистки-ppa

Во время обновления графического интерфейса автоматической Ubuntu, это solicitated, чтобы сделать purge-ppa, произвести чистку PPA... И я делаю это... Но во время ppa-purges ошибка прибывает, и теперь, даже на терминале, выполняющем команду sudo apt upgrade, это говорит:

The following packages have mismatched dependencies:
  libelementary2: It depends: libefreet-bin
                   It depends: libethumb-client-bin
  terminology: It depends: libefreet-bin
                It depends: libethumb-client-bin
E: Mismatched dependencies. Try using -f.

Как предложено я пробую также apt-get -f install но

sudo apt-get -f install
