Apache Cassandra 0.7.6 is just 2 days old, but it shipped with a bug in the debian packaging code that prevents the package from being successfully installed. Since debian packaging is an integral part of the project, 0.7.6-2 comes to fix this issue.
This is the only change[1] that separate 0.7.6-2 from 0.7.6, so if you don't use debian and have already upgraded to 0.7.6, you can safely upgrade 0.7.6-2 or simply skip that version. For the debian users, this will fix the error you may have seen during the upgrade to 0.7.6. As always, all relevant details are in the release notes[2] and please let us know if you encounter any problem[3]. And sorry for the inconvenience. The Cassandra Team.
