The second maintenance release of the 5.5 series of NAV is now out, fixing a couple of serious collection and trap processing issues!

The source code is available for download at GitHub.

New packages for Debian 10 (Buster) and 11 (Bullseye) are available in our APT repository as usual.

Please be extra aware of config file changes. Look out for *.dpkg-dist files in /etc/nav and make sure to update your running config.

The virtual appliance will be updated, but currently, the automated GitHub workflows aren’t working due to changes at GitHub.


  • Fix serious collection breakdown in ipdevpoll by re-generating a valid Python representation of CISCO-ENHANCED-MEMPOOL-MIB (#2494, #2495)
  • Fix broken trap processing in snmptrapd (#2497, #2498)
