I fed all of the information in the original post to Copilot AI and worked iteratively with it to resolve the issue. Here is a summary of the steps I had to take.
Here is a clean, consolidated **summary of the full sequence of steps you had to take** to successfully complete the NagiosXI upgrade on **Oracle Linux 8.10**.
This summary is based entirely on *your actions and my guidance throughout the conversation* (no outside sources required).

**Summary: Steps Required to Successfully Upgrade NagiosXI on OL8**
Below is the exact sequence of fixes and workarounds you had to perform to overcome the multiple repository, dependency, and Python‑build issues that prevented the NagiosXI 2026R1.x upgrade from completing.
***
## **1. Identify root cause of the initial failure**
The upgrade failed because the EL8 dependency bundle shipped with NagiosXI required:
* `ansible` (obsolete, removed from OL8)
* `python39-winrm` (removed from OL8)
* while your system already had `ansible-core 2.16`, which conflicted with all legacy `ansible` versions.
This made the dependency RPM impossible to install normally.
***
## **2. Attempt normal dependency installation (failed)**
Running:
dnf install nagiosxi-deps-el8-2026r1.3-1.noarch.rpm
failed due to missing and conflicting dependencies.
***
## **3. Confirmed that you had both EL8 and EL9 dependency bundles**
Listing revealed:
nagiosxi-deps-el8-2026r1.3-1.noarch.rpm
nagiosxi-deps-el9-2026r1.3-1.noarch.rpm
— confirming the right RPM was present but broken for OL8.
***
## **4. Use workaround: Install dependency RPM with `--nodeps`**
Since the EL8 bundle was not installable through DNF, you bypassed dependency checking:
rpm -Uvh --nodeps nagiosxi-deps-el8-2026r1.3-1.noarch.rpm
This **successfully installed the dependency bundle** despite missing `ansible` and `python39-winrm`.
This was required for the upgrade script to continue.
***
## **5. Fix missing Python environment**
The upgrade script then failed because your system lacked pip:
/usr/bin/python: No module named pip
You resolved this by:
* Installing pip for Python 3.12
* Adding symlinks so NagiosXI’s installer could find them:
<!---->
ln -s /usr/bin/pip3.12 /usr/bin/pip
ln -s /usr/bin/python3.12 /usr/bin/python
This allowed the Python‑based portions of the installer to proceed.
***
## **6. Fix failure compiling the Python rrdtool module**
The installer attempted to run:
pip install rrdtool
This failed twice — first due to missing RRDtool headers (`rrd.h`), then due to missing Python headers (`Python.h`).
You fixed both problems by installing:
### Required packages:
dnf install rrdtool rrdtool-devel
dnf install python3.12-devel
This provided:
* `rrd.h` → required for RRD Python module
* `Python.h` → required for compiling CPython extensions
Once both header packages were present, pip was finally able to build the `rrdtool` Python wheel.
***
## **7. Re-run the upgrade script**
After all fixes were applied, running:
./upgrade
allowed the upgrade to continue successfully through:
* dependency checks
* PHP module checks
* Python module builds
* RRD tool compilation
* XI component updates
And the upgrade completed.
***
#

**Final Result**
You successfully upgraded Nagios XI on Oracle Linux 8 by completing a multi‑step remediation process involving:
* bypassing broken RPM dependencies
* fixing missing system Python tooling
* installing development headers for Python and RRDtool
* ensuring pip and python were available to the installer
* resolving all compile‑time failures for required Python modules
This chain of fixes fully restored the expected environment for NagiosXI’s upgrade script.
