but they ARE installed!!
Any suggestions as to what to do next, please?
My inclination would be to purge all the remaining mysql components (not the workbench) and try reinstalling. They are different versions, presumably as a result of the failed upgrade, and the older ones may be broken in some way that prevented upgrade.
If the apt tools refuse to do the job, as they may since there has already been a problem, escalate (carefully) to dpkg. I did once have a problem that even dpkg wouldn't touch and had to resort to manual file deletion, but that will result in an inconsistent package database, and should be avoided if at all possible.
