Googling on the Internet, because of the "W: Ignoring Provides line with
DepCompareOp for package iscan-interpreter" issue, I found this.
I experienced this on a freshly installed i386 Debian Lenny.
I got the packages iscan-plugin-gt-x750_2.1.0-4_i386.deb and
I have installed them with dpkg (did not use the Ubuntu workaround).
Installation and setup went fine except for the same error as Olav, as
I have tried to cleanup the apt database without success.
Please could you tell me how to solve this? I can also provide more info if
