/usr/share/doc/libcupsys2/changelog.gz: broken symbolic link to `../libcupsys2/changelog.gz'

Which Ubuntu release are you on? Which architecture?

I am on amd64 hardy, and it looks fine to me:

  -rw-r--r-- 1 root root 8733 2008-04-01 22:32 /usr/share/doc/libcupsys2/changelog.gz

It is a regular file, as it is supposed to. Can you please give me the output of

 dpkg --print-architecture
 lsb_release -sir
 dpkg -l libcupsys2 | grep libcups
 ls -ld /usr/share/doc/*cups*

? Thanks!

I'm on amd64 hardy as well:

The problem is with the symlink itself:
lool@fox:~$ ls -l /usr/share/doc/libcupsys2/changelog.gz
lrwxrwxrwx 1 root root 26 2008-04-28 12:08 /usr/share/doc/libcupsys2/changelog.gz -> ../libcupsys2/changelog.gz

debsums cupsys | grep -v OK$ doesn't return any related problem

I'm still confused:

$ wget http://archive.ubuntu.com/ubuntu/pool/main/c/cupsys/libcupsys2_1.3.7-1ubuntu3_amd64.deb
$ dpkg -c libcupsys2_1.3.7-1ubuntu3_amd64.deb | grep changelog.gz
-rw-r--r-- root/root 8733 2008-04-01 22:32 ./usr/share/doc/libcupsys2/changelog.gz

It's not a symlink, it's a regular file as it should be. Also after installation. The postinst doesn't do any symlinking. So I honestly don't know what went wrong on your system, and how to reproduce it.

I don't know either; I didn't fiddle with cupsys stuff at all for sure; for the record, my dpkg/aptitude logs follow

Loic, do you still have this problem on your current system? I am still unable to reproduce it.

I don't; I suspect it was a case of a directory/symlink change in some cupsys package, but we never were able to point out which and it's not reproducible anymore.
