+ <description><p>The last few months me and the other Debian Edu developers have
+been working hard to get the Debian/Squeeze based version of Debian
+Edu/Skolelinux into shape. This future version will use Kerberos for
+authentication, and services are slowly migrated to single signon,
+getting rid of password questions one at the time.</p>
+
+<p>It will also feature a roaming workstation profile with local home
+directory, for laptops that are only some times on the Skolelinux
+network, and for this profile a shortcut is created in Gnome and KDE
+to gain access to the users home directory on the file server. This
+shortcut uses SMB at the moment, and yesterday I had time to test if
+SMB mounting had started working in KDE after we added the cifs-utils
+package. I was pleasantly surprised how well it worked.</p>
+
+<p>Thanks to the recent changes to our samba configuration to get it
+to use Kerberos for authentication, there were no question about user
+password when mounting the SMB volume. A simple click on the shortcut
+in the KDE menu, and a window with the home directory popped
+up. :)</p>
+
+<p>One step closer to a single signon solution out of the box in
+Debian Edu. We already had PAM, LDAP, IMAP and SMTP in place, and now
+also Samba. Next step is Cups and hopefully also NFS.</p>
+
+<p>We had planned a alpha0 release of Debian Edu for today, but thanks
+to the autobuilder administrators for some architectures being slow to
+sign packages, we are still missing the fixed LTSP package we need for
+the release. It was uploaded three days ago with urgency=high, and if
+it had entered testing yesterday we would have been able to test it in
+time for a alpha0 release today. As the binaries for ia64 and powerpc
+still not uploaded to the Debian archive, we need to delay the alpha
+release another day.</p>
+
+<p>If you want to help out with implementing Kerberos for Debian Edu,
+please contact us on debian-edu@lists.debian.org.</p>

+ <description><p>I just posted this announcement culminating several months of work
+with the next Debian Edu release. Not nearly done, but one major step
+completed.</p>
+
+<blockquote>
+<p>This is the first test release based on Squeeze. The focus of this
+release is to test the user application selection. To have a look,
+install the standalone profile and let the developers know if the set
+of installed packages i.e. applications should be modified. If some
+user application is missing, or if there are some applications that no
+longer make sense to be included in Debian Edu, please let us know.
+Also, if a useful application is missing the translation for your
+language of choice, please let us know too.</p>
+
+<p>In addition, feedback and help to polish the desktop (menus,
+artwork, starters, etc.) is appreciated. We would like to ship a nice
+and handy KDE4 desktop targeted for schools out of the box.</p>
+
+<p>The other profiles should be installable, but there is a lot more
+work left to be done before they are ready, so do not expect to
+much.</p>
+
+<p>Changes compared to the lenny based version</p>
+
+<ul>
+<li>Everything from Debian Squeeze
+<ul>
+ <li>Desktop environment KDE 4.4 => the new KDE desktop in
+ combination with some new artwork
+ <li>Web browser Iceweasel 3.5
+ <li>OpenOffice.org 3.2
+ <li>Educational toolbox GCompris 9.3
+ <li>Music creator Rosegarden 10.04.2
+ <li>Image editor Gimp 2.6.10
+ <li>Virtual universe Celestia 1.6.0
+ <li>Virtual stargazer Stellarium 0.10.4
+ <li>3D modeler Blender 2.49.2 (new application)
+ <li>Video editor Kdenlive 0.7.7 (new application)
+</ul></li>
+<li>Now using Kerberos for password checking (migration not finished).
+ Enabled for:
+<ul>
+ <li>PAM
+ <li>LDAP
+ <li>IMAP
+ <li>SMTP (sender verification)
+</ul>
+</li>
+<li>New experimental roaming workstation profile for laptops.</li>
+<li>Show welcome page to users when they first log in. The URL is
+ fetched from LDAP.</li>
+<li>New LXDE desktop option, in addition to KDE (default) and Gnome.</li>
+<li>General cleanup (not finished)</li>
+</ul>
+<p>The following features are not working as they should</p>
+
+<ul>
+<li>No web based administration tool for creating users and groups. The
+ scripts ldap-createuser-krb and ldap-add-user-to-group can be used
+ for testing.</li>
+<li>DVD installs are missing debian-installer images for the PXE boot,
+ and do not set up the PXE menu on eth0 because of this. LTSP
+ clients should still boot from eth1 on thin client servers.</li>
+<li>The restructured KDE menu is not implemented.</li>
+<li>The LDAP server setup need to be reviewed for security.</li>
+<li>The LDAP directory structure need to be reworked.</li>
+<li>Different sets of packages are installed when using the DVD and the
+ netinst CD. More packages are installed using the netinst CD.</li>
+<li>The jackd package fail to install. This is believed to be caused by
+ some ongoing transition, and hopefully should be solved soon. The
+ jackd1 package can be installed manually for those that need it.</li>
+<li>Some packages lack translations. See
+ http://wiki.debian.org/DebianEdu/Status/Squeeze for updated status,
+ and help out with translations.</li>

+ <description><p>I discovered this while doing
+<a href="http://people.skolelinux.org/pere/blog/Automatic_upgrade_testing_from_Lenny_to_Squeeze.html">automated
+testing of upgrades from Debian Lenny to Squeeze</a>. A few packages
+in Debian still got circular dependencies, and it is often claimed
+that apt and aptitude should be able to handle this just fine, but
+some times these dependency loops causes apt to fail.</p>
+
+<p>An example is from todays
+<a href="http://people.skolelinux.org/~pere/debian-upgrade-testing//test-20100727-lenny-squeeze-kde-aptitude.txt">upgrade
+of KDE using aptitude</a>. In it, a bug in kdebase-workspace-data
+causes perl-modules to fail to upgrade. The cause is simple. If a
+package fail to unpack, then only part of packages with the circular
+dependency might end up being unpacked when unpacking aborts, and the
+ones already unpacked will fail to configure in the recovery phase
+because its dependencies are unavailable.</p>
+
+<p>In this log, the problem manifest itself with this error:</p>
+
+<blockquote><pre>
+dpkg: dependency problems prevent configuration of perl-modules:
+ perl-modules depends on perl (>= 5.10.1-1); however:
+ Version of perl on system is 5.10.0-19lenny2.
+dpkg: error processing perl-modules (--configure):
+ dependency problems - leaving unconfigured
+</pre></blockquote>
+
+<p>The perl/perl-modules circular dependency is already
+<a href="http://bugs.debian.org/527917">reported as a bug</a>, and will
+hopefully be solved as soon as possible, but it is not the only one,
+and each one of these loops in the dependency tree can cause similar
+failures. Of course, they only occur when there are bugs in other
+packages causing the unpacking to fail, but it is rather nasty when
+the failure of one package causes the problem to become worse because
+of dependency loops.</p>
+
+<p>Thanks to
+<a href="http://lists.debian.org/debian-devel/2010/06/msg00116.html">the
+tireless effort by Bill Allombert</a>, the number of circular
+dependencies
+<a href="http://debian.semistable.com/debgraph.out.html">left in Debian
+is dropping</a>, and perhaps it will reach zero one day. :)</p>
+
+<p>Todays testing also exposed a bug in
+<a href="http://bugs.debian.org/590605">update-notifier</a> and
+<a href="http://bugs.debian.org/590604">different behaviour</a> between
+apt-get and aptitude, the latter possibly caused by some circular
+dependency. Reported both to BTS to try to get someone to look at
+it.</p>
