Bug#32068: multicd can't reinstall removed package
- Forwarded message from Martin Schulze <[EMAIL PROTECTED]> - Package: dpkg-multicd Version: 0.11 Severity: important I'm awfully sorry but apparently I have to file an important bug report against this pkackage (or dpkg?). It should be fixed before we release slink. First the symptoms: . You install package foo . You mark package foo for removal . You run dpkg --pending --remove . You mark package foo for installation . You try to install it . dselect/multicd/dpkg won't install it . You're lost until you re-run [U]pdate Now the technical part: If you install a package (using dpkg -i foo.deb or dselect) dpkg modifies the record in the available file and replaces it with the proper record from the status file (guessed or experienced by Ruud). As a result of this the available file lacks the fields Filename: MD5sum: and X-Medium: which makes it impossible to install this package again since the methods don't have a chance to find out where the package is located. This doesn't happen with some other methods since they don't depend on the filename being recorded in the available file. Solution: multicd has to copy the Packages files into $methdir/multicd/ and access them directly instead of the available file. Since this needs a redesign of the installation method and I'm somewhat short with time I'd appreciate somebody sending me a proper patch.

I've found this with dpkg-mountable too; it can also happen if a package fails after a certain point in installation (I think). I never quite worked out when it happened, though. > Solution: > > multicd has to copy the Packages files into $methdir/multicd/ and > access them directly instead of the available file. > > Since this needs a redesign of the installation method and I'm somewhat > short with time I'd appreciate somebody sending me a proper patch. The way I solved this was to simply make a copy of the *available* file, after doing dpkg --update-avail in the [U]pdate method, and then parsing that copy in the installation method. If this doesn't work for you, you could always make the copy at the end of the [U]pdate method, and then copy it back at the beginning of the [I]nstall method! (It's not the prettiest method ever, but it would work ...)
