Description
Recently in MDEV-286, the mytop program was added to mariadb-client-5.5 .deb.
But this is a problem - because there is already a standalone debian/ubuntu mytop package. So now install/upgrade of mariadb-client-5.5 conflicts if mytop is already installed.
I do not think there is a pressing need to deliver an alternative to mytop on .deb platforms, so I suggest just removing mytop again from .deb.
However, if we really want to provide an alternative .deb for mytop, then we
- need to put it in a separate package, with proper /usr/share/doc/mytop/* and so on
- need to create correct dependencies so upgrades will go smooth
- need to check existing mytop package - there are a number of patches included, and we need to review them and include relevant ones so users do not loose important functionality in the upgrade

Fix (removing mytop from mariadb-client-5.5 .deb) pushed to lp:maria/5.5
Here is the error that is produced during the apt-get/dpkg operation :
--------

--------
Workaround :
To avoid/correct the problem, remove the mytop package by doing : dpkg -r mytop
Then (if you did try to install the mariadb-client-5.5 package before removing mytop), re-try the package installation by doing : apt-get -f install
There is another small issue on this mytop version if you want it to drop-in replace the debian one : by default the debian packaged mytop will connect on the "mysql" database and the Maria one try to connect on the "test" database, if you dont have an existing database named "test", mytop will fail to start with this error :
Unknown database 'test'
To workaround that, you can add "database=mysql" (as all servers will have a "mysql" database) on your ~/.my.cnf or ~/.mytop (depending on which file you use).
Another solution is to specify the "mysql" databse instead of "test" as the default setting on /usr/bin/mytop at line 80 (but if its not modified upstream you will have to modify that again on the next update).
