xulrunner issue
 

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!

???...no suggestions?

Re: xulrunner issue
 

Uninstall goes wrong because /usr/local/xulrunner/xulrunner --unregister-global segfaults. To uninstall anyway:

- install rootsh and nano using application manager if not installed already
- open xterm
- type: sudo gainroot
- type: nano /var/lib/dpkg/info/xulrunner.prerm
- type on the first line: exit 0
- press ctrl, x, y
- type: dpkg --remove --purge xulrunner
- type: rm -rf /usr/local/xulrunner

I used a slightly different set of steps.

I was successful in uninstalling xulrunner using the "install old version" trick.

I was also successful in uninstalling xulrunner using a modified version of iamthewalrus's steps:
- type: sudo gainroot
- type: nano /var/lib/dpkg/info/xulrunner.prerm
- type on the first line after the lines beginning with "#": exit 0
- press ctrl, x, y, enter
- type: dpkg --remove xulrunner
- type: rm -rf /usr/local/xulrunner

I was also able to get fennec to install using these steps:
(after trying to install fennec unsuccessfully and removing xulrunner, try this)
- type: sudo gainroot
- type: nano /var/lib/dpkg/info/xulrunner.postinst
- type on the first line after the lines beginning with "#": exit 0
- press ctrl, x, y, enter
- apt-get install fennec

The install works, but xulrunner segfaults each time it runs so fennec won't run :( Does anyone else have any thoughts?

I had the same issue with xulrunner and couldnt uninstall. I installed a previous version from mozilla's ftp site and then removed it.
