Back to older packages

[aparigraha]

I got some dependency problems that are related to me trying out some ppa's. I narrowed it down to two packages:

libsoprano4
soprano-daemon

I try to force older versions of the two packages but that just leads to the package manager wanting to remove a heck of a lot of programs that depend on them. So my question is...

Do I really have to remove all those programs and reinstall them again, and if so - what is the sweet command line for that?

EDIT:
Solved that issue by turning to a terminal (Synaptic didn't do it for some reason):

Finding out which version of libsoprano4 and soprano-daemon I had, and which I wanted:

apt-cache policy libsoprano4 soprano-daemon

when I found out which versions I wanted (2.4.2) I just:

sudo apt-get install soprano-daemon=2.4.2+dfsg.1-0ubuntu1.1 libsoprano4=2.4.2+dfsg.1-0ubuntu1.1

Nothing but libsoprano4 and soprano-daemon changed or got removed.
