e2fsprogs is in http://repository.maemo.org - it looks like you don't have the repo configured (Address: http://repository.maemo.org, Distribution: leave blank, Components: free non-free).

If you definately have the above repository configured, have updated the catalogue (either through Application Manager or apt-get update) and still have the same error then post back listing the content of /etc/apt/sources.list.d/hildon-application-manager.list
