Why, when installing the pure-ftpd package, does it want to remove php, munin, etc.?

Question

Accept this solution? [Y/n/q/?]

It seems to say "11 packages upgraded, 63 newly installed, 0 to remove and 527 not upgraded", and then " Remove the following packages ". Couldn't find anything similar on google. I read it but didn't find the answer.
