No, it will install the newest version of whatever it finds. The order of the listings in sources.list only is important if it finds two sources for the *exact* same file. The file then will get installed from the first URI. This is useful if you have a local mirror that may not be up to date with a web mirror. If the local copy is listed first and it contains a file that is the same on the net mirror then the local copy will be installed.
I would not recomend mixing slink and potato sources. Early in the potato development this was possible as slink and potato were not too different and only a few files were updated. But now most files depend in some way on libc6 v2.1 or perl5.005 and will cause major problems if they are installed and you are not willing to upgrade yet. *- On 4 Dec, Bryan Scaringe wrote about "RE: effect of having stable and unstable listed in sources.list" > Opps, > When in doubt, I should read the man pages. > Looks like apt will go through sources.list, and will install the package from > the first source it finds. if I am reading "man sources.list" correctly :) > > Bryan > > > On 04-Dec-1999 Pollywog wrote: >> >> On 04-Dec-1999 Bryan Scaringe wrote: >>> I have seen many examples on this list of people putting entries in >>> sources.list >>> for both stable and unstable trees at the same time.
