I updated my AVR-Ada rpms for Fedora 18 to version 1.2.2. I didn't update Fedora 17 rpms, since Fedora 17 support will end soon anyway, and I felt that the update is waste of time. However, if you need Fedora 17 rpms, you can build them by yourself.
Here is the update procedure for Fedora 18 AVR-Ada 1.2.2 rpms:
sudo yum clean expire-cache sudo yum update --nogpgcheck avr-ada-rts avr-ada-lib
If the update does not work, you can always remove the packages and install them from scratch.
