The following packages have unmet dependencies:
mariadb-client-core-10.0 : Conflicts: mysql-client-5.5 but 5.5.42-1
is to be installed.
Breaks: virtual-mysql-client-core which is
a virtual package.
mysql-client-5.5 : Breaks: virtual-mysql-client which is a virtual
package.
Breaks: virtual-mysql-client-core which is a
virtual package.
mariadb-client-10.0 : Breaks: mysql-client but 5.5.42-1 is to be

Breaks: mysql-client-5.5 but 5.5.42-1 is to be

Breaks: virtual-mysql-client which is a virtual

mariadb-server-10.0 : Breaks: mysql-client-5.5 but 5.5.42-1 is to be
installed.
The following actions will resolve these dependencies:
Keep the following packages at their current version:
1) mariadb-client-10.0 [Not Installed]
2) mariadb-client-core-10.0 [Not Installed]
3) mariadb-server [Not Installed]
4) mariadb-server-10.0 [Not Installed]
Leave the following dependencies unresolved:
5) cqrlog recommends mariadb-server | mysql-server
Accept this solution? [Y/n/q/?]
Abandoning all efforts to resolve these dependencies.
Abort.
root@z6:~>
====================================================================
It's clear what happens now: aptitude/apt try to install
mariadb-server because it's a recommended package and it prefers
mariadb over mysql server since the ordering of these both packages in
debian/control is: "Recommends: mariadb-server | mysql-server" [1].
On the other hand, cqrlog depends on mysql-client which depends on
mysql-client-5.5 which breaks mariadb-client-10.0, a dependency of
mariadb-server-10.0.
Thus, in order to fix this, it should be enough to switch the order
of mariadb-server and mysql-server in the Recommends field in
debian/control such that the first package apt chooses to install
via the Recommends is mysql-server.
Cheers,
Adrian
