How to get rid of orphaned data in package database?

Hello all,

although this is nor causing much problems, I wonder, that in my database are
a lot of packages, which are no more in the repository (for example, all
ia32-*-libs from the time, where ia32-apt-get was active).

Is there a way, to get this cleaned? Those packages are no more available!

There is another thing, which I discovered: apt-file is showing still
/emul/ia32-linux entries, although the packages are no more installed to /emul
.

Or am I wrong?

Cheers

Hans

The last versions of ia32-apt-get added a "Provides: ai32-abi" to all
converted packages. If you had a new enough ia32-apt-get installed
then you can easily grep for that Provides in dpkgs status file.

Saddly ia32-libs fails to conflict with ia32-abi and instead conflicts
with a selection of individual packages (only those in ia32-libs).
But you could build a dummy deb with equivs that conflicts ia32-abi,
install that and remove it again.

Or remove libc6-i386 and then reinstall whatever 32bit stuff you use.

Outdated Contents file?

Hi Goswin!

No, it is not outdated, as I did an "apt-file update" beforfe I checked. IMO
this should do it, doesn't it?

You might try the deborphan package (Orphaned package finder)

"deborphan finds packages that have no packages depending on them. The default
operation is to search only within the libs and oldlibs sections to hunt down
unused libraries."

Oh, its not the packages, I want to get rid off, but the entries in dpkg
database. They appear, although they are no more available.

The Contents file can be outdated on ftp.debian.org too. The archive
only regenerates it a few packages every night.

Maybe apt-file also looks into the dpkg database where you still have
entries.

Reinstall the packages in question. If dpkg thinks you have files in
/emul but they are not there then something is broken.

There is the switch --clear-avail for the dpkg command, but I have no
experience with it.
