Неудовлетворенные зависимости и возможные конфликты? [Дубликат]

Кажется, что я перепутался где-то вдоль линии, и теперь я больше не могу устанавливать что-либо без появления следующего сообщения:

Затем я следую инструкциям и встречаюсь со следующим:

 $ sudo apt-get -f install

 kde-telepathy-minimal is already the newest version (15.04.20ubuntu1).
 kde-telepathy-minimal set to manually installed.
 You might want to run 'apt-get -f install' to correct these:
 The following packages have unmet dependencies:
  kde-telepathy-minimal : Depends: kde-config-telepathy-accounts (>= 15.04.0) but it is not going to be installed
 E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
