Version 1.3.6 doesn't install for signatures do not match the previously installed version; ignoring! about droidwall HOT 9 CLOSED

Please see the changelog: http://code.google.com/p/droidwall/wiki/ChangeLog

The signature has changed in the latest version, so you must uninstall the 
previous
version first.

Hi Dear,
I've already removed the old version. The strange thing is that I've removed 
the apk
and config manually because the app manager doesn't see droidwall installed.

Okay, so it seems that the application was somehow not completely removed.
You may try removing the app package using adb:

adb uninstall "com.googlecode.droidwall"

And then trying to install it again

Nothing!
I get the follow error:
adb uninstall com.googlecode.droidwall
Failure
I tried to reinstall:
adb install -r droidwall-v1_3_6.apk 
510 KB/s (36182 bytes in 0.069s)
    pkg: /data/local/tmp/droidwall-v1_3_6.apk
Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE]

I don't know where but something of the old droidwall is there somewhere...

I've find an occurence in /data/system/package.xml

<package name="com.googlecode.droidwall"
codePath="/data/app/com.googlecode.droidwall.apk" system="false" 
ts="1265027749000"
version="135" userId="10100">

Can I delete just that line or I must remove the entire file?
Or I can modify that?

According to the docs, this error appears "if a previously installed
package of the same name has a different signature than the new package
(and the old package's data was not removed)." 

The important part here is the "(and the old package's data was not removed)".

To avoid messing with your package.xml, you could try re-installing the old 
version
of Droid Wall (you can find it in the Downloads section here) and immediately
removing it again along with the data.

This should remove any reference to the old signature and allow you to install 
the
new version.

zioalex, can you confirm if you were able to install the new version so that I 
can
close this issue? thanks

Rodrigo I'm sorry but meanwhile I've changed ROM so I can't track that problem
anymore. However now after a fresh ROM installation everything is OK! :-D

Okay, closing this issue.
