The KDE3.5 repository has been migrated to a new team PPA, and in the next
month or so I will be heavily modifying the PPA that you are currently
using.
I have updated the instructions on
http://apt.pearsoncomputing.net to
reflect the new team PPA, so please update your system with the new
repository information as soon as possible. Be sure to update the GPG key
as well, by following the instructions under "Add the GPG signing key".
This will not affect your current software installation--the binaries have
been copied directly from the existing PPA with no modifications. I am
only requesting that you update the repository locations in an effort to
prevent future problems, as the old PPA will become a development/testing
PPA in the future.
Thank you, and I hope you enjoy your KDE3.5 installation!
