How to make apt-get install prefer source from local iso?

Question

If there are lots of sources in sourcelist, but I want apt-get to prefer source from local iso, rather than remote mirror, even when remote package is newer than local iso, I want apt-get to choose local iso, what I should do in order to make it works as I want?

This is my configuration of /etc/apt/source.list

deb file:///home/jack/dsk/ lucid main restricted deb http:// us.archive.ubuntu.com/ubuntu/ lucid main restricted deb-src http: //us.archive.ubuntu.com/ubuntu/ lucid main restricted

I run apt-get install ubuntu-desktop, it seems apt-get try to download package from remote mirror:( this is not the thing I want:( I am sure ubuntu-desktop package is in my local iso mirror :( so how to make apt-get choose to install the package from dsk/pool/main/u/ubuntu-meta/ubuntu-desktop_1.197_amd64.deb rather than from http: // us.archive.ubuntu.com/ubuntu/ lucid-updates/main libc6 2.11.1-0ubuntu7.10 ?

find dsk/ | grep ubuntu-desktop dsk/pool/main/u/ubuntu-meta/ubuntu-desktop_1.197_amd64.deb

After this operation, 2,191MB of additional disk space will be used. Get:1 http: // us.archive.ubuntu.com/ubuntu/ lucid-updates/main libc6 2.11.1-0ubuntu7.10 [4,389kB]

of course this is a problem related to software development, what a pity somebody just vote to close it, jesus:( maybe i should give an example that i am install gcc, but not kubuntu-desktop, but so what, they are in the same shoe:( — hugemeow, Jul 26 '12 at 13:54

You are looking for "apt pinning", that is to set preferences between different versions of packages in different repos or branches (stable, testing...).

See apt preferences pin: origin local?

So based in that post you'd have to edit (or probably create because by default it does not exist) the file /etc/apt/preferences and put:

       Package: *
       Pin: origin ""
       Pin-Priority: 999
