The .install for FBReader current has a blank distribution field,
which defaults to the current distribution in Maemo, for Diablo users,
this is "diablo". Unfortunately, FBReader's repository does not have a
Diablo entry, meaning users have to edit this field to read "chinook"
to get the repository to work.
This is a difficult task for new users, and is preventing a lot of
people from installing FBReader under Diablo. There are a few possible
solutions to this, fix the .install to read "chinook", fix the
repository to include a "diablo" distribution, or (the correct and
most helpful solution), upload FBReader and its dependencies to Maemo
Extras (
http://extras-cauldron.garage.maemo.org/HOWTO.html) so we can
do away with having a single repository just for FBReader and users
with new devices will be able to install FBReader right off.
Hopefully this will be resolved soon.
