I'm trying to install sasl2-bin on Natty. However, it depends on db4.8-util, which could not be installed because the default package on Natty is db4.7-util. If I try to install the 4.8 version either from the deb package or from source, it gets deeper into the dependency tree, i.e. it requires more packages to be updated. I did try to manually update them all but at one point (after updating libc-bin) it said I needed to update openssh but that will break a LOT of things for me.
On the other hand, without sasl, I can't run postfix. Could someone please help me resolve this dependency issue?
