Installing Darwin Calendar Server 2.3 on Ubuntu 9.10

Submitted by alex on Sun, 12/13/2009 - 04:47.

Back in my original 'calendarserver on Linux' posting, I wrote about how to set up Apple's Darwin Calendar Server (DCS) on Ubuntu Linux. At the time, I neglected to mention that was Ubuntu 8.10. This turns out to be important, because I have since built a new server using Ubuntu 9.10 and discovered some important differences in the new Ubuntu.

Ubuntu 9.10's calendarserver package is broken

First of all, the calendarserver package provided by Ubuntu is broken and uninstallable. It depends on the python-xml package, which has been removed.

alex@grawp:~$ sudo apt-get install calendarserver

Some packages could not be installed. This may mean that you have

requested an impossible situation or if you are using the unstable

distribution that some required packages have not yet been created

or been moved out of Incoming.

The following information may help to resolve the situation:

The following packages have unmet dependencies:

  calendarserver: Depends: python-xml but it is not installable

E: Broken packages

There are a few bugs open on this subject. You should check on these before going further. The calendarserver package may be fixed by this time, and you can simply install it rather than building the whole thing yourself as described in the remainder of this post.

https://bugs.launchpad.net/ubuntu/+source/calendarserver/+bug/426778
https://bugs.launchpad.net/ubuntu/+source/calendarserver/+bug/403349

Initial Setup

Install some packages DCS needs to run.

sudo apt-get install memcached subversion curl python2.6 python2.6-dev python-setuptools

One caveat... I'm fairly sure this is not a complete list. Until I get another 9.10 VM started up to test my instructions, this is my best guess on prerequisite packages you'll need.

Create a user to run as. I added my user to the 'ssl-cert' group so I can access the system-wide self-signed certificate. You don't need this if you're not going to serve calendars over HTTPS, or if you have your own certificate stored elsewhere.

useradd caldavd -G ssl-cert

DCS uses filesystem extended attributes to store some data. You'll need to enable the 'user_xattr' flag on the filesystem which will host your calendaring data. See my previous post on DCS (linked above) for instructions on how to do this. That post also has more information on configuration you may find helpful.

Now get a copy of the source code. As of now, version 2.3 is the latest DCS release. You can check http://svn.calendarserver.org/repository/calendarserver/CalendarServer/t... to see if anything newer is now available.

sudo mkdir /usr/local/src/caldavd

sudo chown caldavd:caldavd /usr/local/src/caldavd

sudo su - caldavd

cd /usr/local/src/caldavd

svn co http://svn.calendarserver.org/repository/calendarserver/CalendarServer/tags/release/CalendarServer-2.3

Building and Installing

cd /usr/local/src/caldavd/CalendarServer-2.3

./run -h # this will show you what's possible.

./run -i /home/caldavd

DCS includes its own miniature build system which knows how to download all its prerequisites and build them for you. This command './run -i' will download all these various things (like memcached, PyXML, pydirector, Twisted, etc) to /usr/local/src/caldavd, build them, and install everything into the directory you specify. In my example, this all goes into /home/caldavd.

As you might have noticed, DCS uses memcached for caching. When starting up, caldavd starts its own instance of memcached to use, which you can see in the process list of a running DCS instance. Even though ./run -i will download and build memcached for you, DCS will not start that memcached binary. You'll still need to install the memcached package from Ubuntu. This was weird to me at first. I saw that memcache had been downloaded and complied, but my DCS log file was full of errors about memcache not being available.

Setup

I followed a file layout similar to that used by the existing Ubuntu/Debian calendarserver package. The difference is that I put everything in subdirectories of /home/caldavd rather than using system directories. For example, where the package uses /var/run, I used /home/caldavd/var/run.

I did this since I plan to install the Ubunutu calendarserver once it actually works, and I don't want to worry about file clashes between the two servers at that time. Also, user caldavd already has write access in /home/caldavd, so I don't have to go flitting about the filesystem chmoding in various places.

mkdir -p /home/caldavd/var/spool

mkdir /home/caldavd/var/run

mkdir /home/caldavd/var/data

mkdir /home/caldavd/var/docroot

mkdir /home/caldavd/log

You need three configuration files to get DCS to run. There are examples of all three available in /usr/local/src/caldavd/CalendarSserver-2.3/conf.

/usr/local/src/caldavd/CalendarServer-2.3/conf/caldavd.plist
/usr/local/src/caldavd/CalendarServer-2.3/conf/sudoers.plist
/usr/local/src/caldavd/CalendarServer-2.3/conf/auth/accounts.xml

cp /usr/local/src/caldavd/CalendarServer-2.3/conf/caldavd.plist /home/caldavd/usr/local/caldavd

cp /usr/local/src/caldavd/CalendarServer-2.3/conf/sudoers.plist /home/caldavd/usr/local/caldavd

cp /usr/local/src/caldavd/CalendarServer-2.3/conf/auth/accounts.xml /home/caldavd/usr/local/caldavd

caldavd.plist is the main configuration file. Here is the one I'm using... I think you should be able to use this as-is if you follow the file layout I described above. If not, it's pretty easy to read the file and change paths as desired.

Starting DCS

export PYTHONPATH=/home/caldavd/usr/local/lib/python2.6:/home/caldavd/usr/local/lib/python2.6/dist-packages

/home/caldavd/usr/local/bin/caldavd -X -f /home/caldavd/usr/local/caldavd/caldavd.plist -T /home/caldavd/usr/local/bin/twistd

This causes DCS to start up in the foreground (-X). You'll see the server starting up. Watch for any Python exceptions and other errors. As I said, I'm afraid I've not captured all the steps you may need to perform to get DCS running, and any omissions will probably show themselves at this point. Try browsing to https://your.server:8443/ and see what you get! Post comments if you run into errors. I'll be checking my own work soon, and will correct things as needed.

Getting an Init Script

cd /usr/local/src/caldavd

mkdir debian

cd debian

apt-get source calendarserver

cd calendarserver-1.2.dfsg/debian

Have a look at calendarserver.init.d. This requires only very minimal modifications :

# change these

DAEMON=/home/caldavd/usr/local/bin/caldavd

RUNDIR=/home/caldavd/var/run/

SPOOLDIR=/home/caldavd/var/spool/

# add these

DAEMON_OPTS='-f /home/caldavd/usr/local/caldavd/caldavd.plist -T /home/caldavd/usr/local/bin/twistd'

export PYTHONPATH=/home/caldavd/usr/local/lib/python2.6:/home/caldavd/usr/local/lib/python2.6/dist-packages

I also removed the references to /etc/default/calendarserver, and the check_start_daemon() function. After copying the modified script to /etc/init.d/caldavd, I did

update-rc.d caldavd defaults

And now my caldavd will be started and stopped automatically when the machine starts and stops.

Hopefully, Ubuntu or Debian will just fix their package, and these kinds of shenanigans won't be necessary at all. But in case you're like me and want to use Ubuntu 9.10, but also really need DCS to work, I hope this is helpful.

	#1Submitted by georg (not verified) on Wed, 12/23/2009 - 00:32. Thanks for you explanation, tried it today, works great so far. you will need the folowing extra packages on a freshly installed system: curl python-setuptools python-kerberos reply


	#2Submitted by alex on Fri, 01/01/2010 - 15:34. Hello georg. Glad it worked for you. I'll add curl and python-setuptools to my list of prerequisites. As for python-kerberos, how did you determine this was required? I wonder if this is due to the following configuration (from caldavd.plist) <!-- Kerberos/SPNEGO --> <key>Kerberos</key> <dict> <key>Enabled</key> <true/> <key>ServicePrincipal</key> <string></string> </dict> I'm not using Kerberos in my DCS installation, and that config snippet is only hanging around because it was in the example file. I am guessing that if you remove that from your caldavd.plist, you won't need python-kerberos anymore. reply


	#3Submitted by Niall Napier (not verified) on Tue, 01/05/2010 - 16:00. Excellent tutorial. I had an issue where I kept getting: ImportError: No module named zope.interface Despite it being in the dist-packages that the server installed itself. I installed python2.6-zope.interface using apt-get install python2.6-zope.interface and it seemed to resolve the issue, though I'm not sure why it wouldn't load the zope.interface libraries it downloaded and installed. reply

	#5Submitted by alex on Tue, 01/12/2010 - 19:47. Magnus : Did you install memcached from the Ubuntu repositories? DCS will download & compile memcached, but it still tries to start /usr/bin/memcached rather than the one it built. Update : I discovered that the file /home/caldavd/usr/local/lib/python2.6/dist-packages/twistedcaldav/config.py is apparently the one which starts memcached. It searches your PATH for the memcached executable. You can either install the Ubunutu package, so /usr/bin/memcached is available, or you could add the location of an alternate memcached binary to your PATH. It's probably not a good idea to mess around with the memcached-1.2.6 which is downloaded & compiled by DCS. It's configured to install into /usr/local/src (or whereever you build DCS from). Changing this might break the DCS build, and running binaries out of a src directory just seems weird to me. reply

This is produced when I attempt to write an item to the calendar using iCal, such as for the test user. The access.log at this point shows: "PUT /calendars/__uids__/d817aaec-7d24-5b38-bc2f-6369da72cdd9/calendar/3CEFA48C-9DF5-440A-9092-9A2F1A3DAFF1.ics HTTP/1.1" 500 201 "-" "DAVKit/4.0.1 (730); CalendarStore/4.0.1 (973); iCal/4.0.1 (1374); Mac OS X/10.6.2 (10C540)" i=8443 t=3148.6 or=1 When I did the build, it didn't download or build memcached. The memcached version installed by the 'apt-get install' is 1.2.2.

	#17Submitted by alex on Tue, 02/16/2010 - 19:28. Arjan : 'service caldavd restart' fails for me as well, though I'm able to 'service caldavd stop' and 'service caldavd start'. I only did some basic hacking on the init script, so it seems there's a bit more polish needed there. Make sure you've added a PYTHONPATH value to the init script. I formerly had this in the 'start' action, but I've moved it up next to the DAEMON_OPTS at the top of the init script, and updated the Getting An Init Script section of this tutorial. Double-check that, try again, and let us know how it goes. I'll try to look at this again soon, and maybe get my updated init script up on GitHub or somewhere else so others can just download the final version rather than needing to follow these instructions on what changes to make. reply

	#20Submitted by alex on Mon, 03/22/2010 - 15:06. tassos : You wrote "The connection to 10.1.1.5:12008 was interrupted while the page was loading." What is supposed to be listening on that port? My server doesn't have anything configured to listen there. Your error log shows you have an SSL-enabled calendarserver on port 8443, but there was an error due to the process being unable to access a file (maybe the SSL private key?). "2010-03-22 11:37:24+0200 [-] [caldav-12008] [-] [calendarserver.tap.caldav.CalDAVServiceMaker#error] Unable to set up SSL context factory: [('system library', 'fopen', 'Permission denied'), ('BIO routines', 'FILE_CTRL', 'system lib'), ('SSL routines', 'SSL_CTX_use_PrivateKey_file', 'system lib')]" reply


	#21Submitted by tassos (not verified) on Sat, 03/27/2010 - 16:54. alex the calendar server was instructed to do http requests at 12008 just as it does https requests in 8443 the ssl certificates were not created, and I try to use this port for the plain text service reply


	#22Submitted by alex on Sat, 03/27/2010 - 21:27. I suggest you try removing the HTTPS configuration for port 8443, and focus on getting the HTTP configuration working on port 12008. You might try 'telnet 10.1.1.5 12008'. This would allow you to send & receive raw HTTP traffic, and might give you a better idea why the connection is being interrupted. Your /var/log/syslog may contain some clues as well. reply


	#23Submitted by Sammy Spets (not verified) on Mon, 04/12/2010 - 08:52. Hi there alex, Thanks for writing up these instructions. I followed them to get Calendar Server 2.4 installed on Ubuntu 9.10. Works like a charm. I did hit a hardcoded bug in upgrade code since I wanted to upgrade all data from 1.2. The bug will affect all linux installations. Anyone wishing to get around this will find the patch at: http://trac.calendarserver.org/ticket/337 Other than that, the server is running beautifully with access from iCal on both Mac (using /principals/__uids__//) and iPhone (using /principals/users//). Thanks again alex! reply


	#24Submitted by Chris (not verified) on Sat, 05/29/2010 - 21:15. The dependencies should also contain readline6-dev and libzip-dev. Thus the apt-get command should be changed to: sudo apt-get install memcached subversion curl python2.6 python2.6-dev python-setuptools readline6-dev libzip-dev Thank you for sharing! reply
