Apt dependency hell

[Michael ODonnell]

You should be able to get a sense of which MYSQL-related packages are
currently installed thus:

  function dgrep () { COLUMNS=300 dpkg -l | tr -s '[:blank:]' ' ' | grep $*; }
  dgrep -i mysql

...and you should be able to get a sense of which packages are available
to you in the repositor{y,ies} thus:

  apt-cache search mysql | fgrep -i mysql | sort

...and you might then be able to make some human-in-the-loop decisions
about which of your current packages you need to get rid of:

  apt-get remove mysql-client-4.1 mysql-server-4.1     # ...for example

...before you then explicitly install the ones you want:

  apt-get install mysql-server-5.0 mysql-client-5.0    # ...for example
