I recently upgraded our lab from 2.6.0 to 2.7.7. I am not sure about your upgrade path, but during my upgrade, I tried to directly upgrade to 2.7.7 using 2.7.7 packages but it failed and complained missing elements of 2.6.2 and some other libraries. So I tried to install packages from 2.6.2 rpm packages and I still got the errors for missing 2.6.1 elements and other libs. So I need to first upgrade to 2.6.1, then to 2.6.2 and then to 2.7.7. Maybe part of your problem is because of this. From my experience, ISC team did a very good job that the only external dependencies we need is liblog4cplus and maybe there’s another I cannot recall, but I do remember I also needed to upgrade liblog4cplus to newer version as well.
One useful command I found is: yum localinstall <package_name> On Apr 30, 2025, at 1:51 PM, Scott Rakow <srs...@gmail.com> wrote: Hey Darren, Thanks for your reply. I have rebuilt my server to a patched RedHat 9.5 VM, created an repo for Kea, which includes the 2.6.2 RPM's for isc-kea-common, isc-kea-ctrl-agent, isc-kea-dhcp4, isc-kea-doc, and isc-kea-hooks. When running the install I am getting told that "nothing provides" libboost_system.so.1.66.0 and liblog4cplus-1.2.so.5. I get this error for all four of the app RPM's I am trying to install. In a short search I was able to install libboost_system via the boost-system RPM, which is 1.75.0-8.el9. When retrying the install I am getting the same error. Are you specific to the 1.66 so library? Or am I still missing something?

Having this repository installed will make it easy for you to update to new point releases. Additionally, when upgrading beyond 2.6.2 (to 3.0.0, for example), it will be a simple matter of installing the new repository and executing `dnf upgrade`. As far as things to be aware of when upgrading from 2.4 to 2.6, there are a few sources of information. - Here: https://kb.isc.org/docs/changes-to-be-aware-of-when-migrating-to-kea-2-6-0 - and here: https://gitlab.isc.org/isc-projects/kea/-/wikis/Release-Notes/release-notes-2.6.0 - and 2.6.1: https://gitlab.isc.org/isc-projects/kea/-/wikis/Release-Notes/release-notes-2.6.1 - and finally 2.6.2: https://gitlab.isc.org/isc-projects/kea/-/wikis/Release-Notes/release-notes-2.6.2 As for your question about whether HA will function with one server on 2.4 and one on 2.6, the answer is: it might. 2.6 has a new failover mode (hub and spoke) and some new messaging that is introduced. The unknown messages will be ignored by the server that doesn't understand them (2.4) but this could potentially cause some problems for the server sending them (2.6). If the 2.6 server is your standby (in a hot-standby relationship), and no failover events occur, you'll probably be ok. It is best to not let this situation persist for long. Also note that if you are using database storage at all, Kea will refuse to start if the database schema is not updated. See here: https://kea.readthedocs.io/en/kea-2.4.1/arm/admin.html#upgrading-a-mysql-database-from-an-earlier-version-of-kea (MySQL) or here: https://kea.readthedocs.io/en/kea-2.4.1/arm/admin.html#upgrading-a-postgresql-database-from-an-earlier-version-of-kea (PostgreSQL).
