Не удалось установить libgdal на сервере ubuntu 20.04.2

это не проблема «репозитория вселенной», этот пост был предложен участником форума Как мне включить репозиторий «вселенная»? . Это связано с тем, что не хватает некоторых зависимостей, см. Ответ ниже.

Как установить libgdal на сервер ubuntu 20.04.2? Я получил следующие ошибки:

$ sudo apt install libgdal-dev

...
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
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libgdal-dev : Depends: default-libmysqlclient-dev but it is not going to be installed

Следующие решения не работают для меня:

• добавить дополнительный ppa (см. answer-1 )

• установить дополнительный . deb (см. answer-2 )

Согласно совету @ N0rbert, вот результат выполнения команды:
