Package: moodle Version: 2.5.3-3 Severity: serious Having libjs-yui-common and libjs-yui-common installed, an upgrade of moodle from 2.5.3-2 to -3 results in loss of a large number of files from these two packages.
What I think happens here is that dpkg first sets the symlink of /usr/share/moodle/lib/yuilib/3.9.1/build to /usr/share/javascript/yui3, and then goes on to remove all the files from /u/s/m/lib/yuilib/3.9.1/build/ that are no longer contained in the new version of moodle. It *will* follow the symlink and this results in removal of these files from /usr/share/javascript/yui3 instead. This is perfectly reproducable for me: install -2, then upgrade to -3. dpkg -L libjs-yui3-common | while read f; do [ -e "$f" ] || echo "$f"; done will list a lot of missing files afterwards. Apart from being a policy violation this bug also cripples the functionality of moodle itself. My suggestion would be: 1. elide the dir removal from preinst 2. don't include the symlink in the package contents 3. remove the dir and create the symlink in the postinst When transplanting the dir removal code, remember that [ -d ... ] will return true for a symlink to a directory. br, -- Robert Bihlmeyer -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
