Sorry, but you lost me here. apt-cache show libjpeg62-dev/stable libjpeg8-dev/stable | grep -e '^Package:' -e 'Provides:' Package: libjpeg62-dev Package: libjpeg8-dev Provides: libjpeg-dev So, libjpeg62-dev isn't providing libjpeg-dev in stable – and also not in testing or unstable. (It is also why apt-get is automatically deciding that you mean libjpeg8-dev as it is the only provider, if there would be more, you would need to choose) Also, libjpeg8-dev conflicts with libjpeg62-dev, so they can't co-exist -> your first install request is indeed an impossible situation.
