clang is still in unstable: $ apt-show-versions -a clang clang:amd64 1:3.0-6.2 install ok installed clang:amd64 1:3.0-6.2 wheezy ftp.debian.org No testing version clang:amd64 1:3.2-19 unstable ftp.debian.org No experimental version clang:amd64/unstable 1:3.0-6.2 upgradeable to 1:3.2-19 > > Even though this appears to be a downgrade of libclang-common-dev, > > the installation should obviously be forced in such a case. > > Downgrades are not supported in Debian, so its even more obvious that > APT shouldn't actively trying to destroy your system without heavy force > applied as old packages might be unable to read their new conf file formats, > irreversible maintainer-script actions (which the maintainer has to code > of course - at best bug-free as it is already done for the more common > "upgrade" scenario), … > > Given that you hit this problem only if a maintainer hasn't cared too much > for the upgradeability of the package, I wouldn't have too much hope that > the maintainer has cared all that much for downgrades … If you assume that's an error from the maintainer, then OK. > Beside: Detecting this would be pretty hard and full of cornercases > (especially as yours is already one as it crosses source-package boundaries): > It wouldn't be that great if a package is removed from testing and the > package gets therefore downgraded to a version from stable for example… But this can be preferable if the removed package has security bugs and has been removed for this reason (the user wouldn't be aware of that with the current behavior of apt). Perhaps another solution rather than downgrading is to warn the user that something is wrong. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <http://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon) -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
