Linux version installation problem

[[r4]]

Sorry for reviving such an old topic (I guess it's zombie now, aint' it? "More braaaaains..." comes to mind :P). I've just found newer version of BFilter being available, happily downloaded it's "package" version - planning to do some direct upgrade - and found myself in trouble again.

My pretty well exercised method desribed above allowed me to install BFilter... but it won't alow me to remove it! Installation of a new version consist simply of removing an old 1.1.1 and installing 1.1.2 instead - as far as I understand what's being done here. The problem is - my system insists that the administrator installed a program and he's the one and only allowed to remove it! I tried "sudo" and switching permanently to root account, still to no avail.

Code:

sudo ~/.local/bin/package install ./bfilter-gui-1.1.2.x86.package

runs pretty graphical installer, which fails. Any attempt to remove it manually fails also. Would you be so kind and post any suggestion regarding this matter? I'm eager to update, however I can wait at least that one day - tomorrow Ubuntu 7.10 will be released.
