Нет рабочего стола 19.04 после обновления с 18.10

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:

Я попробовал следующее, чтобы исправить apt, но безуспешно:

sudo apt clean
sudo apt update
sudo apt update --fix-missing
sudo apt upgrade
sudo apt dist-upgrade
sudo dpkg --configure -a
sudo apt install -f

Некомментированные строки в /etc/apt/sources.list:

deb http://ch.archive.ubuntu.com/ubuntu/ disco main restricted
deb http://ch.archive.ubuntu.com/ubuntu/ disco-updates main restricted

Выполнение startx приводит к:

/etc/X11/xinit/xserverrc: 3: exec: /usr/bin/X: not found
xinit: giving up
xinit: unable to connect to X server: Connection refused
xinit: server error

Вывод uname -a:

Linux XPS13 5.0.0-13-generic #14-Ubuntu SMP Mon Apr 15 14:59:14 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

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.
