Hi, After trying to get 4.1.1 to run on Debian some month ago I decided to bite the bullet and also package it. I am not a debian developer, so it is only available from my own repository : https://tree.se/debian/ DISCLAIMER - USE AT YOUR OWN RISK. It might not be ready for production but I'd like some feedback to the quality of the package. Instructions how to install it is also available on https://tree.se/debian/ The release do not support ipv6, i had to disable the patches.py Runtime error in response to not finding a solution to the problem with --reactor=select as described here : http://lists.macosforge.org/pipermail/calendarserver-dev/2012-November/00156... Still a new twisted seems to be in the works. It is available in experimental. Debian bug #689983 already requests better IPv6 support. The changelog is : calendarserver (4.1.1-1) unstable; urgency=low * Updated to new released version v4.1.1 * Disabled patches.py until twisted 12.2.0-1 is released * Applied upstream patch for python-sqlparse 0.1.4 ( http://trac.calendarserver.org/ticket/759 ) * Debianized bootstrapdatabase.py * Added caldavd uid/gid to default file -- Fredrik Unger <debian@tree.se> Mon, 10 Dec 2012 16:15:11 +0100 It should be just to install, enable in /etc/default/calendarserver, start, and http://localhost:8008/ should be available. It would be iteresting to get some feedback and cooperation from the people running calendarserver on debian, best practices etc that I can put in the documentation. Currently I am running an old instance of the package on my server, and have limited experience with configuring calendarserver for groups etc. I do use LDAP for my installation and will try to document that too. The package is not extensively tested. Sincerely, Fredrik Unger
