Я недавно обновился с 18.10 до 19.04, и рабочий стол больше не доступен. Система загружается в терминал. Если я попытаюсь sudo apt install ubuntu-desktop
, я получу длинный список ошибок зависимости:
Reading package lists...

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

Я попробовал следующее, чтобы исправить apt, но безуспешно:

sudo apt dist-upgrade
sudo dpkg --configure -a
sudo apt install -f

Любые предложения будут высоко оценены это могло бы помочь восстановить apt
и, в конечном счете, вернуть жизнь в мою среду desktop
!
Хорошо, может быть полезно для дальнейших читателей.
В таких случаях с The following packages have unmet dependencies
, один из способов найти ошибку - использовать цепной метод:
Итак, в этом случае вы сделали:
sudo apt install ubuntu-desktop
Это дало ошибку:
...
The following packages have unmet dependencies:
ubuntu-desktop : Depends: gdm3 but it is not going to be installed
...
Затем вы должны сделать:
sudo apt install gdm3
Это либо вызовет новую ошибку неудовлетворенных зависимостей, либо вы найдете истинную причину ошибки. В первом случае вы будете повторять процесс с другим неудовлетворенным пакетом, во втором случае вы просто решаете проблему.
