Apt-get upgrade problems

[". ." <pyro@message.hu>]

Hi,

I have a strange problem with apt-get. I installed a package manually
with dpkg after apt-get ran into a conflict and since then apt-get does
not upgrade anything. It gives:
Reading Package Lists... Done
Building Dependency Tree... Done
Calculating Upgrade... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded
for upgrade, dist-upgrade and dselect-upgrade as well. I did run apt-get
update it seems to get the new package lists but no effect when trying
to upgrade. I use the unstable distribution. Could anyone help? I'm
pretty much a newbie.

Thanks!
