Seed-DB not working

[Rudolph Bott]

Hey List,

I upgraded to 3.6.0 and now to 3.6.3 but still no luck - the seed-db
page is not working :(

I always end up with this error:

Any hints? I executed all the database update scripts, restarted apache etc.

What linux distro are you using? Did you install via Werner's deb-package or
from source?

To me, it looks like you haven't installed pysnmp-se. There's also a known
problem with multiple pysnmp versions in Ubuntu, if that's what you're using.

Hey Morten,

sorry - I forgot to add the relevant information:

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=9.04
DISTRIB_CODENAME=jaunty
DISTRIB_DESCRIPTION="Ubuntu 9.04"

The following pysnmp packets are installed:

ii python-pysnmp-common 4.1.9a-1
ii python-pysnmp2 2.0.9-1
ii python-pysnmp4 4.1.9a-1
ii python-pysnmp4-apps 0.2.6a-1
ii python-pysnmp4-mibs 0.0.5a-3

I installed from source (at some point I installed from source because
the deb's weren't available yet and kept upgrading the source version
since then).

Any hints? :)

Yes. Install python-pysnmp-se, then uninstall python-pysnmp2 and
python-pysnmp4.

NAV 3.6 uses pysnmp-se, but Ubuntu has a bug where pysnmp2 will always be
loaded if it is installed - which is why I recommend uninstalling the other
versions.
