pfBlocker-NG-devel 3.2.0_3 not uninstalling on 23.01

hefferbub

I'm having the same problem on 23.01, but I'm using 3.2.0.3 non-DEVEL version (supposedly these are the same?).

It is definitely not deleting the pfblockerng configuration entries in config.xml.

How can I safely remove an old config and start over?

Thanks

Have you uncheck this?: Bildschirmfoto 2023-04-06 um 13.19.44.png

@fireodo Thanks for the suggestion.

I did check that, but there seems to be a bug in the code that deletes the old configuration (as shown in the original post of this thread).

So my config entries remain, and get re-used when I reinstall the package.

I did have one idea of how to deal with this—if I do a manual backup and tell it not to back up package configuration, I could probably then restore from that to clean it up.

I have not tried it yet, however.

Did you reboot pfSense after you deleted the package including the settings. I seem to recall that you need to do that in order to clear all the old settings in the config file, other files, etc?

@jdeloach Yes. Still the error persists.

You need to UNcheck the "keep settings" box. Otherwise the config is left in the config file, for example to keep settings after a pfSense version upgrade.

re: PHP error, with the migration to PHP 8 there have been quite a lot of PHP errors that were found in rarely used code. If it can be replicated you can look for it and make a report at https://redmine.pfsense.org.

@steveits It IS unchecked an the stack trace STILL triggers.

I tried uninstalling the devel version today (with Save Config unchecked), and it did not produce any errors.

However, when I download the config.xml, there are still several hundred lines of PFBlocker entries.

@lohphat Any reason why you cant upgrade to _4 then remove? If there is regression in an old package but not in the new one i dont see the redmine going places.

lohphat

@michmoor Well you mentioned the issue of config crud still in the config file after removal. I included that in the bug description. So even if it doesn't throw a stack trace under _4 the config cleanup is still broken.

michmoor

@lohphat true.

I've installed 3.2.0_4 and I'm still getting the stack trace.

@lohphat darn…I’ve seen this somewhere..Reddit maybe? I hope you get your answer but I would recommend posting on the pfblocker subreddit. The maintainer does chime in.

lohphat

@michmoor He's responding to the Redmine bug.

michmoor

@lohphat Very cool.
