Where did you get the instructions to do this?
They seem to be outdated.

The PPA ppa:~rolfbensch/ubuntu/sane-git simply does not exist (any more).
The providers of PPAs are free to do anything with their PPAs, and they can also delete them.
This is not within responsibility of Launchpad services. Launchpad services just provides the plattform for hosting.

I guess that you need
sudo add-apt-repository ppa:sane-project/sane-git

Well, that's true - the owner of that PPA appears to have deleted it. That's up to them.

Launchpad itself only provides the hosting service for PPAs. You'll need to contact the owner of this PPA ( to ask specific questions about it.

Can you help with this problem?
