core: Applying Unbound blacklist fails with error

• I have read the contributing guide lines at https://github.com/opnsense/core/blob/master/CONTRIBUTING.md
• I am convinced that my issue is new after having checked both open and closed issues at https://github.com/opnsense/core/issues?q=is%3Aissue

Describe the bug

After adding a new entry in the Unbound blocklist whitelist (going from 2 to 3 elements) and pressing Download&Apply, it waits a while and then I am greeted with an error box stating

Error updating blocklists
An error occurred during script execution. Check the logs for details

Backend log shows

Timeout (120) executing : unbound dnsbl
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.

Subsequent attempts at pressing Download&Apply immediately return with the error box. I am currently unable to save at all.

To Reproduce

Steps to reproduce the behavior (I am not sure how reproducible it is on other installs):

1. Have Unbound blocklist active with Blocksite.list Fraud,Malware,Phishing,Ransomware,Scam; EasyList; EasyPrivacy; WindowsSpyblocker (spy)’
2. Have two elements in whitelist: foo.com, .foo.com
3. Download&Apply
4. Use for a while
5. Later, add third element bar.com to whitelist
6. Press Download&Apply

Expected behavior

Applies without trouble

Describe alternatives you considered

Rebooting the box perhaps? Not an option until at least the weekend. And I’d be workarounding, nox fixing things 😃
