This is an update to my message from yesterday. And it is somewhat for information to others at the same point on the learning curve. First, the role of repositories was not clear to me before. In particular, the need to enter the appropriate repositories into the Application Manager even if using apt-get or a green "click to install" script in the Software Catalog. These pages helped: maemo.org > Community > Application Catalog > FAQ > What is a repository? http://maemo.org/community/wiki/applicationrepositories/ maemo.org > Community > Wiki > ApplicationRepositories http://maemo.org/community/wiki/ApplicationRepositories maemo.org > Community > Wiki > CodeNames http://maemo.org/community/wiki/codenames/ After adding repositories I can now easily install those applications that are listed in the Application Manager. But second, the relationship between a repository address provided in a HowTo, the actual location of the repository, and the real location of files still eludes me. Like the e2fsprogs package I referred to yesterday.
