snmpd fails to upgrade

[Martin Hagelin]

When upgrading snmpd, I get the following error:

dpkg: error processing snmpd (--configure):
 subprocess installed post-installation script returned error exit status 128
Errors were encountered while processing:
 snmpd

I had the same problem with the previous upgrade of snmpd and I was able to fix it by changing the snmpd.postinst file. I moved the two lines for confmodule to the beginning of the file, see patch below.

Now it works.

I've run into this problem and applied the change as a workaround -- and it allowed the installation to succeed.

Actually I think there are two problems with this package:

1) When upgrading it does not stop the snmpd daemon and when it tries to recreate the user snmp it fails ( see https://bugs.launchpad.net/ubuntu/+source/net-snmp/+bug/573391 )

2) The problem reported here

In my case I had to stop the daemon and then apply the modification on the snmpd.postinst file. Only then the upgrade was sucessfully applied.

This bug was fixed in the package net-snmp - 5.4.2.1~dfsg0ubuntu1-0ubuntu4
