With apt pinning [1], in /etc/apt/preferences , I have learned that one can have certain packs from another release than the rest of the system, seemlessly (?) with apt-get and the other tools, for example like this for w3m-el-snapshot:
Package: * Pin: release a=testing Pin-Priority: -10 Package: w3m-el-snapshot Pin: release a=testing Pin-Priority: 800 But is there a way to find out/confirm from which release is a certain pack? I know about 'aptitude show' but save for the version, which I suppose one could Google and compare (poor man's solution IMO), it doesn't seem to say what I can see. Neither does 'dpkg -l'. So is there a way to do this with shell tool(s)? TIA [1] https://wiki.debian.org/AptPreferences -- underground experts united http://user.it.uu.se/~embe8573
