You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 akonadi-backend-mysql : Depends: mariadb-client-core-10.3 but it is not going to be installed or
                                  virtual-mysql-client-core
 mysql-client : Depends: mysql-community-client (= 8.0.19-1ubuntu19.10) but it is not installable
 mysql-community-server : Depends: mysql-community-server-core (= 8.0.19-1ubuntu19.10) but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

И когда я работаюsudo apt-get -f install, это спрашивает меня разрешение удалить, таким образом:

The following packages will be REMOVED:
  mysql-client mysql-community-server mysql-server

Что мне делать? Спасибо на Вашем времени.
