You will most likely receive cryptic, unhelpful dpkg errors.

If this is the case, try the command below.

sudo aptitude purge mysql-common mysql-client mysql-server && sudo aptitude install mysql-server-4.1 mysql-client-4.1

This should purge whatever is left of the MySQL 5.x installation, and then install the MySQL 4.x version. If this fails, proceed to bang head against nearest hard object.

From the system with your desired software:

    dpkg --get-selections > mysoftwarelist.txt

To the reinstalled or fresh system:

    dpkg --set-selections mysoftwarelist.txt
    sudo dselect
