I'd like to install the movabletype-opensource package for version 5.0 I currently have Ubuntu 10.04 installed. How do I install the experimental package? Do I need to add a site to my apt sources?
Currently, version 4.3.3-1 is in the lucid/10.04 repositories (4.3.4-1 is in the maverick/10.10 and natty/11.04 repositories). Debian does not have any 5.0 versions, and a quick PPA search on Launchpad did not turn anything up either.
If you would prefer to install movabletype-opensource from an actual deb package, you might be interested in this bug on the Debian BTS reporting that 5.0 is available upstream and requesting and updated package or this Request For Help Bug.
