Comment 5 for bug 131865

Here the problem is worse.
My first try, before reading this thread, was to remove flashplugin. Then I got another error in the prerm script as well. Then I edited both script files (prerm and postinst), removing all those strange chars. But the prerm is still broken. I get the error message:
/var/lib/dpkg/info/flashplugin-nonfree.prerm: line 30: syntax error near unexpected token `;;'

Apparently apt tries to remove the package, before reinstalling it.
I've already looked into the script file, but found nothing near that line different from the rest. Well, I'm not a shell script programmer...
Can anyone help me?

Thanks.
