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: dbconfig-mysql : Depends: mysql-client but it is not going to be installed or mariadb-client but it is not going to be installed or virtual-mysql-client E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

I get the same error. . No luck with above mentioned solutions :-(
