Comment 6 for bug 1377426

Same problem still here on bionic.

Roundcube-core depends on libapache2-mod-php which of course will pull in apache2 no matter what else.

That dependency is listed as libapache2-mod-php or php which seems to be superfluous since PHP is unavoidable anyway.

And while I'm at it there's also a hard dependency on a database driver which is not necessary if I'm not going to use a DB.

Those dependencies really need some work.
