Could not install 'nspluginwrapper': segfault in post-install script

[janl]

Binary package hint: update-manager

Upgrading from 10.10 to 11.04 with update manager I get this message with a button to "Report bug". The reason given for the failure is "subprocess installed post-installation script returned error exit status 139".

Actual dpkg output:

Worked around by

dpkg --purge remove flashplugin-installer acroread nspluginwrapper

Thanks for your report.

This error is caused by a segfault in nspluginwrapper postinst script

Moving to nspluginwrapper

I had a similar experience. For me it was the googletalk plugin that caused the crash.

I simply removed the link in /usr/lib/firefox/plugins and rerunned dpkg --configure -a to solve the problem. Then I created the link again.

I have now
1. Reinstalled nspluginwrapper
2. It still produced the sigsegv
3. I removed google-talkplugin (apt-get --purge remove ...)
4. nspluginwrapper now does not sigsegv anymore.

I will assume that google-talkplugin is the root cause of this problem.

[Risto Pekkala (risto-pekkala-se)]

Fixed with:

- sudo apt-get purge nspluginwrapper
- sudo apt-get purge google-talkplugin
- sudo apt-get install nspluginwrapper
- sudo apt-get install google-talkplugin

Then I reinstalled my previously removed flash:
- sudo apt-get install flashplugin-installer

All seem ok.

Thank you, Risto. Your comment #6 made away with the error.
