[sane-devel] Question SANE and Canon Scanner

[Kelly Price]

Have you tried Rolf's PPA?

sudo add-apt-repository ppa:rolfbensch/sane-release
sudo apt-get update
sudo apt-get upgrade

The -dev packages usually install headers and such that allow folks to
program against libsane.

At worst, uninstall the Mint versions and use the PPA.
