Ошибка зависимости: невозможно установить Anjuta IDE

Question 1

Я не могу установить Anjuta Studio в Ubuntu 15.04, используя Gnome 3.16 DE.

Это вывод терминала:

shivam@shivam-Inspiron-3521:~$ sudo apt-get install libjavascriptcoregtk-2.4.9-0

The following information may help to resolve the situation:

Question 2

Можно установить следующие пакеты

libjavascriptcoregtk-1.0-0 (2.4.8-1ubuntu)
libjavascriptcoregtk-3.0-0 (2.4.8-1ubuntu2)
libjavascriptcoregtk-4.0-18 (2.6.2+dfsg1-4ubuntu1)

но нет libjavascriptcoregtk-2.4.9-0.

И у Вас был PPA ppa:webkit-team в Вашей системе прежде и поэтому libjavascriptcoregtk-3.0-0 (2.4.9-0ubuntu1~15.04~webkitteam1) установленный. Если Вам нужен PPA (снова) переходят в конце моего ответа и игнорируют следующие шаги.

Проблема, libwebkit2gtk-3.0-25 из Стандарта Репозитории Ubuntu нуждается точно libjavascriptcoregtk-3.0-0 (2.4.8-1ubuntu2).

Быстрое решение, понизьте пакет libjavascriptcoregtk-3.0-0 через

sudo apt-get install libjavascriptcoregtk-3.0-0=2.4.8-1ubuntu2

но необходимо использовать команды ниже для понижения всех пакетов, обновленных PPA ppa:webkit-team

sudo apt-get install ppa-purge
sudo apt-add-repository ppa:webkit-team
sudo apt-get update
sudo ppa-purge ppa:webkit-team

В будущем использовать ppa-purge удалить PPA из Вашей системы.

При необходимости в PPA добавьте его снова и используйте его, и проблема будет решена, также

sudo apt-add-repository ppa:webkit-team
sudo apt-get update
sudo apt-get dist-upgrade
