{{Warning|Dapper (i.e. 6.06) is no longer supported. Use newer Ubuntu templates.}} The ubuntu template is an OpenVZ [[OS template]] that allows you to run ubuntu dapper in your [[VEcontainer]], as opposed to the normal Debian stable or Fedora.
''Please note, that this package is really minimal, you must even install your own language pack!''
==How do I get it?==
You may download it from one of the following places:
* [http://dudcore.net/ubuntu/ubuntu-6.06-i386-minimal.tar.gz Original place] (dudcore.net)
* [http://download.openvz.org/contrib/template/precreated/ubuntu-6.06-i386-minimal.tar.gz download.openvz.org]
* One of the [[OpenVZ download mirrors]]
You must place this file in <tt>/vz/template/cache/</tt> directory on your [[hardware node]].
==How do I create a VE container that uses this template?==All you have to do is simply create a normal VE container but specify ubuntu-6.06-i386-minimal as the template. For example:
<pre> vzctl create 1002 --ostemplate ubuntu-6.06-i386-minimal </pre>
 
''Please note that in order to get the correct network settings and more, you must copy the debian configuration file(debian.conf) to ubuntu.conf. This is because Openvz does not yet reconize that ubuntu is its own os, and falls back to another linux distribution. Usually this file is located in /etc/vz/dists but can very depending on your distribution. For CentOS/Fedora this will be located in /etc/sysconfig/vz-scripts/dists. See {{bug|190}}.''
==How do I set it up?==
You can either do those modifications on already existing VEcontainer, or, if you want these changes to be incorporated into your template, create a temporary VEcontainer, do these changes, stop the VE container and tar the result into the same template file. Well, the first thing you *must* do is install a language pack. You can do this by typing in<pre> apt-get install language-pack-en </pre> <pre>Bug alert: I (Shane Hathaway) got the following error when I tried to install language-pack-en.  debconf: apt-extracttemplates failed: Bad file descriptordpkg: dpkg - error: PATH is not set. I patched the problem by typing "export PATH". Even though the path is set, for somereason it is not exported by default. I also added "export PATH" to /etc/profile .</pre>
Well, the first thing you *must* do is install a language pack. You can do this by typing in <pre> apt-get install language-pack-en </pre>
Then you should create another user. To do this, just type in <pre> adduser bob </pre>
You will probably want to install some other basic utilities: <pre>apt-get install man traceroute wget</pre>
==How was this template created?==
This package was created using debootstrap, and using the ubuntu dapper repositories. There were some hacks that needed to be done to the enviorment to get it working correctly, mainly for networking. The system was bootstrapped on a real ubuntu dapper system with ovzkernel-2.6.8. I checked it with my own server and then my webhosts, and it works correctly.
 
==Network issues==
If the template seems to have no working network it most probably needs more time to bring up the interfaces. The issue is, that
<pre>
/etc/network/if-up.d/ntpdate
</pre>
wants to set the clock during network start and runs into a very long timeout. Since ntpdate is not needed at all inside a container this script can simply be deleted. And Magic - the container starts up as fast as I would expect it to and all network interfaces are up and running at once.
