Invalid symbolic links in /usr/share/doc/libsane

[Alexander Gieg]

The following symbolic link, installed by the libsane package (1.0.19-23ubuntu7), is invalid unless libsane-dev is also installed:

/usr/share/doc/libsane/supported.html -> html/sane-mfgs.html

So, IMHO it would be a good idea to either let libsane-dev create it when installed, or to move the html/sane-mfgs.html file into libsane itself.

My system: Ubuntu 9.04 (upgraded from 8.10)

According to the upstream bug, this is a problem created downsream in ubuntu and debian.

Please could you see if this bug still exists in karmic (libsane version 1.0.20-4ubuntu3)

I filed bug #472919 while going through the output of cruft(8), but it's a dup of this.

$ find -L $(dpkg -L libsane) -maxdepth 0 -type l -ls
22258000 0 lrwxrwxrwx 1 root root 19 Oct 31 16:11 /usr/share/doc/libsane/supported.html -> html/sane-mfgs.html
$ apt-file search /usr/share/doc/libsane/html
(no result, path not found in the archive)

up to date karmic, debsums -c is clean.
ii libsane 1.0.20-4ubuntu3 API library for scanners

However, the problem may be worse now than when this bug was opened.
from apt-file list libsane-dev:
libsane-dev: /usr/share/doc/libsane-dev/html/sane-mfgs.html

 So unless one of /usr/share/doc/libsane{,-dev} is a symlink to the other, the supported.html symlink needs to be to
../libsane-dev/...

This has been fixed in Precise (if not earlier): libsane depends on libsane-common, which now provides html/sane-mfgs.html.

jani@saegusa:~$ dlocate sane-mfgs.html
libsane-common: /usr/share/doc/libsane/html/sane-mfgs.html
jani@saegusa:~$ LC_ALL=C apt-cache depends libsane | grep libsane
