Hi, the Debian packages of Calendarserver 1.2 development branch just entered the Debian archive. It's in the experimental distribution so by adding: deb http://ftp.debian.org/debian/ experimental main and running: apt-get -t experimental python-twisted-calendarserver calendarserver you should get everything that's needed. Please have a look at: /usr/share/doc/calendarserver/README.Debian on howto get things going. Cheers, -- Guido
