Comment 1 for bug 163255

Confirming this on a G3 iMac. Fixed for the time being using a patched package linked from here, which doesn't annoy Update Manager so much:

Commands used to apply the temporary fix:

wget http://launchpadlibrarian.net/8296818/liboil0.3_0.3.12-1_powerpc.deb
sudo dpkg -i liboil0.3_0.3.12-1_powerpc.deb
