I'm reaching out to see if anyone has any suggestions. I've searched the forums time and time again and have attempted all the different proposed solutions and yet i am still unable to uninstall xulrunner. the version installed is: 1.9.1b1pre-2008923171103

i keep getting errors that state:

Could not exec dpkg!
E: Sub-process /usr/bin/dpkg returned an error code (100)

now i've done different things such as autoremove, --purge, the dpkg method and so on and so on but with no success. i even tried reinstalling xulrunner as well as fennec since that is the application it is tied to. still no luck. any help would be greatly appreciated.

thanks in advance!
