How can I install pessulus on Ubuntu 12.10? We are currently upgrading hardware and Ubuntu 12.10 supports the multi-touch screen that we're about to use.
When I enter the command
apt-get install pessulus in the command line, I get this message:
Reading package lists... Done Building dependency tree Reading state information... Done Package pessulus is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'pessulus' has no installation candidate
What do I need to do to install pessulus? I'd be grateful for any help.
