For the stable distribution (etch), this problem has been fixed in version 0.2.2-1etch1. Due to a technical limitation of the archive management scripts, the fix for the old stable distribution (sarge) needs to be postponed by a few days. We recommend that you upgrade your yarssr packages. Upgrade instructions - --------------------wget url will fetch the file for you dpkg -i file.deb will install the referenced file.
