+ How to test Debian Edu Jessie despite some fatal problems with the installer +
+
+ 26th September 2014 +
+
+

The Debian Edu / Skolelinux +project provide a Linux solution for schools, including a +powerful desktop with education software, a central server providing +web pages, user database, user home directories, central login and PXE +boot of both clients without disk and the installation to install Debian +Edu on machines with disk (and a few other services perhaps to small +to mention here). We in the Debian Edu team are currently working on +the Jessie based version, trying to get everything in shape before the +freeze, to avoid having to maintain our own package repository in the +future. The +current +status can be seen on the Debian wiki, and there is still heaps of +work left. Some fatal problems block testing, breaking the installer, +but it is possible to work around these to get anyway. Here is a +recipe on how to get the installation limping along.

+ +

First, download the test ISO via +ftp, +http +or rsync (use +ftp.skolelinux.org::cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso). +The ISO build was broken on Tuesday, so we do not get a new ISO every +12 hours or so, but thankfully the ISO we already got we are able to +install with some tweaking.

+ +

When you get to the Debian Edu profile question, go to tty2 +(use Alt-Ctrl-F2), run

+ +

+nano /usr/bin/edu-eatmydata-install
+

+ +

and add 'exit 0' as the second line, disabling the eatmydata +optimization. Return to the installation, select the profile you want +and continue. Without this change, exim4-config will fail to install +due to a known bug in eatmydata.

+ +

When you get the grub question at the end, answer /dev/sda (or if +this do not work, figure out what your correct value would be. All my +test machines need /dev/sda, so I have no advice if it do not fit +your need.

+ +

If you installed a profile including a graphical desktop, log in as +root after the initial boot from hard drive, and install the +education-desktop-XXX metapackage. XXX can be kde, gnome, lxde, xfce +or mate. If you want several desktop options, install more than one +metapackage. Once this is done, reboot and you should have a working +graphical login screen. This workaround should no longer be needed +once the education-tasks package version 1.801 enter testing in two +days.

+ +

I believe the ISO build will start working on two days when the new +tasksel package enter testing and Steve McIntyre get a chance to +update the debian-cd git repository. The eatmydata, grub and desktop +issues are already fixed in unstable and testing, and should show up +on the ISO as soon as the ISO build start working again. Well the +eatmydata optimization is really just disabled. The proper fix +require an upload by the eatmydata maintainer applying the patch +provided in bug #702711. +The rest have proper fixes in unstable.

+ +

I hope this get you going with the installation testing, as we are +quickly running out of time trying to get our Jessie based +installation ready before the distribution freeze in a month.

+ Suddenly I am the new upstream of the lsdvd command line tool +
+
+ 25th September 2014 +
+
+

I use the lsdvd tool +to handle my fairly large DVD collection. It is a nice command line +tool to get details about a DVD, like title, tracks, track length, +etc, in XML, Perl or human readable format. But lsdvd have not seen +any new development since 2006 and had a few irritating bugs affecting +its use with some DVDs. Upstream seemed to be dead, and in January I +sent a small probe asking for a version control repository for the +project, without any reply. But I use it regularly and would like to +get an updated version +into Debian. So two weeks ago I tried harder to get in touch with +the project admin, and after getting a reply from him explaining that +he was no longer interested in the project, I asked if I could take +over. And yesterday, I became project admin.

+ +

I've been in touch with a Gentoo developer and the Debian +maintainer interested in joining forces to maintain the upstream +project, and I hope we can get a new release out fairly quickly, +collecting the patches spread around on the internet into on place. +I've added the relevant Debian patches to the freshly created git +repository, and expect the Gentoo patches to make it too. If you got +a DVD collection and care about command line tools, check out +the git source and join +the project mailing +list. :)
