@Nelson,

That’s a really quick fix from Opennms community.. Hope it will help other users..

The issue was solved yesterday: turns out the deb packages for the libraries **jicmp** and **jicmp6** were missing in the repository for the i386 architecture. Both are now available and openmns deb package can be installed.

@Nelson,

Thanks for your research, but I too don’t have any solution for this, better we should wait till it fixed in the next update..

(expected stable but got opennms-24)

That error can be fixed just changing the stable keyword in /etc/apt/sources.list.d/opennms.list repository file with opennms-24.

But after that I get dependency errors from apt when I’m trying to install OpenNMS (trying to install those packages leads to another dependency package errors).

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 opennms : Depends: opennms-server (= 24.1.2-1) but it is not going to be installed
           Depends: opennms-webapp-jetty (= 24.1.2-1) but it is not going to be installed
           Recommends: opennms-source (= 24.1.2-1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Changing the repository from opennms-24 to opennms-23 or opennms-22 leads to another unmet dependency errors with PostgreSQL.

Seems obvious the Debian OpenNMS repository has broken dependency packages, so, there’s any other alternative to this or just have to wait to be fixed…?
