I recently upgraded to Jessie, using sysvint-core as my init and am having
some printer problems.
I got the printer working. CUPS was apparently uninstalled during the
upgrade. I had noticed that some CUPS files were being removed, but it
looked like replacements for them were being installed. Anyway, I installed
CUPS, found what driver it wanted (printer-driver-hpcups) and installed it,
printer-driver-hpcups is a dependency of hplip, so I would have expected
it to be already installed.
No matter which tool I tried to run, with the exception of hp-check, I get
the following error:
# hp-setup
Traceback (most recent call last):

This is strange. libsnmp15 was in wheezy and a dependency of hplip 3.12.
In Jessie, hplip is 3.14 and depends on libsnmp30. You seem to have
hplip 3.14, so why it's looking for the file above is a mystery.
This is the version of libhpmud0 that is currently installed on my system,
even after purging and reinstalling several times. That date seems rather
old. Almost half a year BEFORE the Jessie release:
/var/cache/apt/archives$ ls libhp*
-rw-r--r-- 1 root root 170600 Nov 8 2014 libhpmud0_3.14.6-1+b2_amd64.deb
That seems to be the correct version for jessie.
Is there a newer version that I should be getting? This version says that it
requires libsnmp30, and that is what it brings in, but then it actually
seems to try to use libsnmp15. Is this a bug? If so, how do I report it?
Apparently, this has been reported already.

It looks like this is not due to the current version of libhpmud trying
to use old libnetsnmp15, but due to old hpmud-related files being left
around.
Googling this error, it comes up all over the place. In multiple
distributions and years. I saw it as early as 2009 and just about every
year since then. I haven't had any trouble with this prior to Jessie, but
it certainly seems to have been a problem for others. Is this a problem with
dependencies in libhpmud0 not being kept up correctly? But that doesn't
explain why it would be a problem across multiple distributions. I'm
confused (obviously). Any further ideas?
I found an Ubuntu bug report from mid-2014:
https://bugs.launchpad.net/ubuntu/+source/hplip/+bug/1245010
It looks like you can run
locate hpmudext.so
locate libhpmud.so
and after that, for each entry <file> resulting from these commands,
ldd <file> | grep netsnmp
If any snmp15 lines show up, then <file> might be the culprit, so you
can try removing <file>.
(If the snmp15 error goes away, but you still have problems, you might
try reinstalling hplip and libhpmud0 again.)
