There must be possibility in synaptic, apt etc to see what repository current package belongs to. E.g. $ apt-cache search synaptic shows now next: ... synaptic - Graphical front-end for APT Should be : synaptic - Graphical front-end for APT {Dedalus, Base} Also must be additional filter in synaptic to filter by repositories.
There is such possibility both in synaptic and apt. In synaptic one can see repositories on the "Versions" tab in the properties window. In apt it is needed to use "apt-cache showpkg": $ apt-cache showpkg synaptic Package: synaptic Versions: 0.56-alt0.3(/var/lib/apt/lists/_home_setup_ALTLinux_Sisyphus_i586_base_pkglist.classic)(/var/lib/rpm/Packages) 0.56-alt0.2(/var/lib/apt/lists/_home_setup_ALTLinux_hasher_i586_base_pkglist.hasher) ... There is theoretical possibility to search by repository. One need to create new filter searching by Origin... but the thing is that functionality doesn't work in synaptic, the implementation has bug... Could you please create new bug for this? ;-)
