Please help

I tried to uninstall rq and reinstall even upgrade django-rq but isn't work.

That should almost never be required, and may make things worse. Netbox has its own hermetic virtualenv. Although it doesn't specify all dependencies directly, so you don't know exactly what combination of packages you'll get, major dependencies like django-rq are specified: e.g.

# grep django-rq /opt/netbox/requirements.txt
django-rq==2.10.2

Don't change these.

To ensure that everything is installed correctly, run:

cd /opt/netbox
./upgrade.sh

To debug your problem, you'll need to give more info.

1. What version of Netbox?
2. What platform/OS?
3. Direct install or docker?
4. Explain what you did that caused the backtrace to be displayed, or where you see it
5. Show the full backtrace. Put three backticks (```) on a line of their own, before and after the backtrace, so that it formats correctly in github markdown.
6. Show what non-default settings you have in your configuration.py

The critical line is truncated:

Nov 13 13:48:06 netbox-01 python3[307501]: ImportError: cannot import name 'Connection' from 'rq' (/opt/netbox/venv/lib/python3.12/site-packages/rq/__init__.py). Di>

Please use journalctl -eu netbox-rq --no-pager to get the full error message.

Also:

1. Show the contents of /etc/systemd/system/netbox-rq.service
2. Show these permissions:

ls -l /opt/netbox/venv/lib/python3.12/site-packages/rq/__init__.py
ls -l /opt/netbox/venv/lib/python3.12/site-packages/rq/connections.py

Finally, given that this is RHEL, look in dmesg and see if there are any SELinux enforcement errors shown.

Someone else had the same problem. Solution here: #18014 (reply in thread)

Upgrade to v4.1.5 or v4.1.6 will fix it.

The problem is that the rq package is the wrong version (not django-rq), and prior to v4.1.5, the package version was not pinned.
