Sorry. I tried to take a shortcut and you ended up with a "mess". Let's see if we can clean that up. Please read this mail to the end before you start doing stuff. > $ dpkg-query -W libsane > libsane:amd64 1.0.23-3ubuntu3.1 > libsane:i386 1.0.25+git20150528-1ubuntu2 That surprised me a bit so I pulled down the Linux Mint 17.2 64bit image and fired up a virtual machine to make sure that I knew what is going on. Looks like Linux Mint installs a number of packages for both 32 and 64 bit architectures and libsane is one of them. > So I then redid the command on the amd64 deb: > > $ sudo dpkg -i libsane_1.0.25+git20150528-1ubuntu2_amd64.deb > [...] > libsane:amd64 depends on libsane-common (= 1.0.25+git20150528-1ubuntu2); > however: > Version of libsane-common on system is 1.0.23-3ubuntu3.1. > libsane:amd64 depends on libgphoto2-port12 (>= 2.5.6); however: > Package libgphoto2-port12 is not installed. > > dpkg: error processing package libsane:amd64 (--install): > dependency problems - leaving unconfigured > Errors were encountered while processing: > libsane:amd64 I obviously forgot about the libsane dependencies. My bad. I have reproduced your situation in that virtual machine of mine. > Now my query came out as follows: > $ dpkg-query -W libsane > libsane:amd64 1.0.25+git20150528-1ubuntu2 > libsane:i386 1.0.25+git20150528-1ubuntu2 To back out of this, use: sudo apt-get install libsane=1.0.23-3ubuntu3.1 libsane:i386=1.0.23-3ubuntu3.1 This will downgrade the currently "installed" versions and get you back to a clean slate. You can check with: sudo dpkg --audit Things are okay if that produces no output. Now on to getting the libsane package from Ubuntu's wily installed. > SANE is still not recognizing my Canon. Do the errors above give you > any new ideas for me to try? First let's add the Ubuntu repositories to your list of package archives the way it's supposed to be done. Copy the attached 00-ubuntu-wily.list to /etc/apt/sources.list.d/ and update your available package information, like so sudo cp 00-ubuntu-wily.list /etc/apt/sources.list.d sudo apt-get update This should download a couple of files from archive.ubuntu.com. Next, lest you end up turning your Linux Mint into Ubuntu's wily almost completely ;-), copy the attached 00-ubuntu-wily.pref to /etc/apt/preferences.d/ sudo cp 00-ubuntu-wily.pref /etc/apt/preferences.d Now we are ready to: sudo apt-get install -t wily libsane I tried this on my virtual machine and all went well. Hope it will for you to. In case you are curious about what's going on, have a look at the following manual pages (using the man command): sources.list apt_preferences apt-get Hope this helps, -- Olaf Meeuwissen, LPIC-2 FSF Associate Member since 2004-01-27 Support Free Software Support the Free Software Foundation https://my.fsf.org/donate https://my.fsf.org/join GnuPG key: F84A2DD9/B3C0 2F47 EA19 64F4 9F13 F43E B8A4 A88A F84A 2DD9
