Then you can't do it.  It's just that simple.

Never use --force, unless it's just a temporary workaround for a known, and 
fully understood packaging error, which will quickly be rectified by an 
upgrade to a later package release, which will not use --force.

Your updated mysql package will probably fail in some subtle way at some 
point, or, worse yet, continue to work but give incorrect results.  Or, 
other software that has an explicit dependency on your older version of 
MySQL will malfunction or lose stability, in some way.

--force is not a "fix", for a dependency issue.  It's a workaround for a 
known packaging bug.

You do not have any packaging bugs.  Your package is fine, it's just not 
compatible with the rest of the software that you have installed.  And using 
--force is not going to fix it.

Using --force is equivalent to sticking your head into a pile of sand, and 
hope that this will fix all your problems.
