Network scanning on HP1522n fails because it looks for libhpmud.so instead of libhpmud.so.0

[Thierry Carrez]

Binary package hint: hplip

On Jaunty, using hplip 3.9.2-3ubuntu4
I have a MFP1522n and try to use network scanning (not USB).
Starting xsane it tries to connect to the printer and fails with the following error in syslog:

xsane: scan/sane/soapht.c 67: unable to load restricted library: libhpmud.so: cannot open shared object file: No such file or directory

Creating a link to /usr/lib/libhpmud.so.0 works around the issue:
  sudo ln -s /usr/lib/libhpmud.so.0 /usr/lib/libhpmud.so
If you install the hp-plugin network scanning then works perfectly.

Confirmed in 9.04. Creating the symlink is the only thing needed to solve this problem.

Symlink resolved my issue too.

Adding the symlink resolved my issue also

Can anyone check whether it is still a problem with Karmic (or with HPLIP 3.9.6b)?

Till:
Removing the symlink I created to work around the issue in jaunty, it runs fine on current karmic.
Cheers.

This works in Jaunty for the HP CM1312 MFP N as well. The error code is slightly different, Xsane claims that is has encountered and i/o failure, but this fix resolves the problem.

The bug is present on a fresh install of Karmic 64-bit using printer HP m1120N MFP, the syslog shows :

scan/sane/marvell.c 66: unable to load restricted library: libhpmud.so: Ne peut ouvrir le fichier d'objet partagé: Aucun fichier ou dossier de ce type

Creating the symbolic link to /usr/lib/libhpmud.so.0 fixes the problem.

Same on Karmic, symlink solved issue.

[LionelD (lionel-duriez)]

Bug still present on 10.04 64-bit, the symbolic link fixes the problem.

[Savvas Radevic (medigeek)]

Setting as confirmed, as stated above

[Thierry Carrez (ttx)]

It works ok here on lucid without the symlink... so I'm wondering why LionelD needs it.

LionelD: please confirm that it still affects you (try removing the added /usr/lib/libhpmud.so -> /usr/lib/libhpmud.so.0 symlink).
If it's still present, you should probably open a 1120N-specific bug since 1522N is fixed AFAICT.

If anyone still experiences it with Lucid on the 1522N, please reopen the bug.

I have an M1522n and I'm running Lucid 64bit. Creating the symbolic link didn't help.

I have machines upgraded from older Ubuntu version and they can still do network scan without problems, so what I did was to download hplip directly from http://hplipopensource.com and install as I always did before.

Now network scanning works.
