Apt with two dists

[vaidhy@wwdg.com]

Hi All,

 I have a local mirror of debian with hamm and slink for binary-i386. 
When I point apt at my mirror and ask it to update the packages, it 
gets confused with hamm and slink. 

For eg: kernel-package 5.06 is in hamm and 5.07 is in slink. apt tries
to read 5.06 from slink. 

What should I do if I have to install packages from both hamm and slink?

Thanks,
Vaidhy

PS: my sources.list look like

file://debian/debian unstable main contrib non-free non-us
file://debian/debian stable man contrib non-free non-us
