Canon PIXMA MX860 and Ubuntu 11.10

When I upgraded the laptop to Ubuntu 11.10, the Canon inkjet quit working.  I tried reinstalling the drivers, but it refused (even with --force-architecture).  I tried (for a few hours) building the drivers, but it was just one thing after another.

Eventually, I found this:

sudo add-apt-repository ppa:michael-gruz/canon
sudo apt-get update
sudo apt-get install cnijfilter-mx860series
sudo apt-get install scangearmp-mx860series

Good news is, it prints again. Bad news, no landscape or double-sided printing.
