So, as Dave Hibberd found out, the problem is that Ubuntu is shipping mysql-* as mysql-* and Debian is shipping mariadb-* as mysql-*.
See his original comment with more details here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1073790#10 One possible Debian-side solution could be changing the virtual-mysql- client-core and virtual-mysql-server-core to mariadb-client-core and mariadb-server-core, default-mysql-server to mariadb-server and removing the default-mysql-server-core dependency. That would cause dependency issues on systems that already have mysql-server-8 installed, but since CQRLOG does not seem to work with mysql anymore (only with mariadb), it should not be a big problem, at least in my opinion. The other possible solution would be to patch this in Ubuntu. However, I am not sure whether the CQRLOG package has any Ubuntu maintainers and also it would probably break auto-sync of the package from Debian. CQRLOG should also fix their MySQL 8 support if possible. That would probably be the best solution. It looks like that there sadly are not other possible fixes to this issue. ** Bug watch added: Debian Bug tracker #1073790 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1073790 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872002 Title: cqrlog needs to depend on mariadb instead of mysql To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cqrlog/+bug/1872002/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
