--- Comment #33 from Aldo Latino <aldo...@gmail.com> --- After many tests (either on my work computer and in some VirtualBox machines) I discovered that this problem happens to me when I install the package mysql-server which removes some Akonadi related packages[1]. In other words, if I don't install mysql-server, Akonadi works fine. After the installation of mysql-server, Akonadi stops working. In this situation, since I need a LAMP server on my machine, I have to perform some actions in order to make Akonadi work with mysql-server. [1] MySQL is correctly installed but these are some of the lines printed during the installation process: Preconfiguring packages ... dpkg: mariadb-client-core-10.3: dependency problems, but removing anyway as you requested: akonadi-backend-mysql depends on mariadb-client-core-10.3 | virtual-mysql-client-core; however: Package mariadb-client-core-10.3 is to be removed. Package virtual-mysql-client-core is not installed. Package mariadb-client-core-10.3 which provides virtual-mysql-client-core is to be removed. -- You are receiving this mail because: You are watching all bug changes.
