I'm in version 4.8.1
So the patch is working with your command.
$ patch -p2 -d /usr/share/pyshared < 1625.diff
- patching file nav/portadmin/snmputils.py
- patching file nav/smidumps/dnos_switching_mib.py
- patching file nav/web/portadmin/views.py
But when I restart apache here's the error in the log

I'm trying to apply the patch following the instructions but I have some
problems.
The instructions talk about only 1 file and the patch 1625.diff concern 3
files (snmputils.py, dnos_switching_mib.py and portadmin/views.py).
Is there a way to apply to all files directly ?

As I see in 1625.diff, the first file concerned is snmputils.py so I tried
with this file

Hi there,

all the files are in the Python libraries of NAV, so they should all be
patchable using this command (optional --dry-run first, of course):

  patch -p2 -d /usr/share/pyshared < 1625.diff

BUT, I think one crucial bit of information that was missing from the
instructions: The patch is based on NAV 4.8. If you are are still on
4.7, there may be differences that cause the patch to fail.
