Package: apt Version: 1.8.4 Severity: normal Dear Maintainer, after updating the system, including the exiv2 and libexiv2-dev packages, relaunching the update command:
$ apt-get upgrade Lettura elenco dei pacchetti... Fatto Generazione albero delle dipendenze Lettura informazioni sullo stato... Fatto Calcolo dell'aggiornamento... Fatto I seguenti pacchetti saranno RETROCESSI: exiv2 libexiv2-dev 0 aggiornati, 0 installati, 2 retrocessi, 0 da rimuovere e 0 non aggiornati. È necessario scaricare 0 B/999 kB di archivi. Dopo quest'operazione, verranno occupati 0 B di spazio su disco. Continuare? [S/n] ^C if I repeat the update command (already executed), there is always an update to be performed on the same packages. As far as I can see these packages appear in two repository: $ apt-cache policy exiv2 libexiv2-dev exiv2: Installed: 0.27.2-3 Applicant: 0.27.2-3 Version table: *** 0.27.2-3 100 100 http://debian.fastweb.it/debian experimental / main amd64 Packages 100 / var / lib / dpkg / status 0.27.2-3 750 750 http://www.deb-multimedia.org sid / main amd64 Packages 0.25-4 700 500 http://debian.fastweb.it/debian stable / main amd64 Packages 700 http://debian.fastweb.it/debian sid / main amd64 Packages libexiv2-dev: Installed: 0.27.2-3 Applicant: 0.27.2-3 Version table: *** 0.27.2-3 100 100 http://debian.fastweb.it/debian experimental / main amd64 Packages 100 / var / lib / dpkg / status 0.27.2-3 750 750 http://www.deb-multimedia.org sid / main amd64 Packages 0.25-4 700 500 http://debian.fastweb.it/debian stable / main amd64 Packages 700 http://debian.fastweb.it/debian sid / main amd64 Packages The problem is, that although the package has been installed from the multimedia repository (pin 750), however in the apt-cache policies it appears to be (incorrectly) installed by experimental repository, so the misunderstanding is created and the package is considered to be reinstalled. Is it possible to fix the problem?
