Unbound blocklist update script failing in 22.7.2

[GorillaxJax]

Hey all,

I recently started using OPNsense and am loving it so far.

I just stopped using a PiHole and swapped to using the unbound blocklists to simplify my network. Unfortunately, I have been running into issues when I try to click "Download and Apply" on the Blocklist screen. I tracked down under System -> Log files -> Backend that the actual script was failing:

Severity	Process	Line
Error	configd.py	[c6b3537c-2d37-4922-bb08-7dd6c4c0ffc1] Script action failed with Command ' /usr/local/opnsense/scripts/unbound/blocklists.py && /usr/local/opnsense/scripts/unbound/wrapper.py -b ' returned non-zero exit status 99. at Traceback (most recent call last): File "/usr/local/opnsense/service/modules/processhandler.py", line 482, in execute subprocess.check_call(script_command, env=self.config_environment, shell=True, File "/usr/local/lib/python3.9/subprocess.py", line 373, in check_call raise CalledProcessError(retcode, cmd) subprocess.CalledProcessError: Command ' /usr/local/opnsense/scripts/unbound/blocklists.py && /usr/local/opnsense/scripts/unbound/wrapper.py -b ' returned non-zero exit status 99.

Any ideas on how to fix this? I've tried the usual audits, restarting services, restarting the whole machine, and checking for updates.

Easiest option to reveal the actual error is to execute the following on a console:

Code Select Expand


/usr/local/opnsense/scripts/unbound/blocklists.py && /usr/local/opnsense/scripts/unbound/wrapper.py -b


confgd only tells you which action failed, but doesn't dump the full output.

Good point. I ran it in command line but it seems to have executed successfully, no errors thrown.

After running it again from the web GUI it seems like it timed out:

Code Select Expand

configd.py Timeout (120) executing : unbound dnsbl

And now every time I try to run it from the GUI it throws that same error I've posted before. It maybe seems to be timing out trying to download a block list?

[AdSchellevis]

the timeout isn't very unusual if processing and downloading take a long time (>120 seconds), it doesn't sound logical that the manual commands don't fail when executed manually, connectivity issues maybe? failing random.

Well once I ran it in command line again I checked the unbound logs and noticed that it was actually updating blocklists in the background.

Code Select Expand

blocklist download done in 992.24 seconds

It seems to be that if the Download and Apply button/script is ran from the Web GUI, if it takes more than 120 seconds it is killed as it is deemed 'stuck'. If ran manually, it will continue to update until all lists are updated even if it takes 16.5 minutes.

I seem to have fixed it. The fix for me was I turned on DNS64 and as such when it was trying to resolve Blocklist DNS rules it defaulted to the AAAA address when some of them only have a A address.

Once I turned off DNS64 and reloaded Unbound the blocklist was updated in only a few seconds instead of 900.

Thanks for the help and pointing me to a few other troubleshooting steps!
