After 'smbpasswd -e Administrator' on tjener and 'rpc net join -S tjener -U administrator' on the workstation the system showed up in the GOsa² gui as windows-workstation.

Various tests later, here's the updated recipe including instructions how to migrate from squid to squid3, how to deal with changes concerning cups and how to clean up the system. So far, I haven't found anything that doesn't work, but it needs testing, confirmation and review by others before the wiki chapter https://wiki.debian.org/DebianEdu/Documentation/Jessie/Upgrades can be updated. ===================================== How to upgrade from wheezy to jessie. ------------------------------------- Please note that the following instructions apply to a default Debian Edu main server installation (desktop=kde, profiles Main-Server, Workstation, Thin-Client-Server). (For a general overview concernig wheezy to jessie upgrade, see: https://www.debian.org/releases/testing/releasenotes) Don't use X, use a virtual console, log in as root. Read all debconf information carefully, choose 'keep the local version currently installed'; in most cases hitting return will be fine. Press 'q' to quit the apt-listchanges pager once you've read the information. Make sure the current system is up-to-date. ------------------------------------------- apt-get update apt-get -y upgrade Remove diversion; debian-edu-config's postinst seems to do it too late. ----------------------------------------------------------------------- dpkg-divert --remove /usr/share/pam-configs/krb5 rm /usr/share/pam-configs/edu-krb5 Avoid to mess up the Kerberos configuration via cfengine. --------------------------------------------------------- cp /etc/krb5.conf /etc/krb5.conf.backup Do the actual upgrade. ---------------------- sed -i 's/wheezy/jessie/g' /etc/apt/sources.list apt-get update apt-get -y dist-upgrade apt-get -f install apt-get -y dist-upgrade (Repeat the last two commands if dpkg exits with an error code.) Install squid3 as replacement for deprecated squid. --------------------------------------------------- apt-get -y install squid3 service squid3 stop Apply debian-edu configuration (takes some time). ------------------------------------------------- cfengine-debian-edu -D installation Replace squid with squid3, keep the cache; a new swap file will be generated and the cache index be rebuilt upon first squid3 start. ------------------------------------------------------------------ service squid stop umount /var/spool/squid sed -i 's#/var/spool/squid#/var/spool/squid3#' /etc/fstab mount /var/spool/squid3 service squid3 start apt-get -y purge squid squid-common Get back the right Kerberos file. --------------------------------- cp /etc/krb5.conf.backup /etc/krb5.conf Make GOsa² work with new php version. ------------------------------------- rm /etc/gosa/gosa.secrets cp /etc/gosa/gosa.conf.orig /etc/gosa/gosa.conf gosa-encrypt-passwords Install newly split out cups package needed for networked printing. ------------------------------------------------------------------- apt-get -y install cups-browsed Install additional package to make PXE work. -------------------------------------------- apt-get -y install pxelinux Update PXE configuration. ------------------------- debian-edu-pxeinstall Install missing packages; the package names were obtained using '/usr/lib/debian-edu-config/testsuite/taskpkgs | grep error:' after the step above. --------------------------------------------------------------- apt-get -y install browser-plugin-libreoffice gosa-plugin-netgroups \ killer libnss-myhostname goplay icedtea-7-plugin tmispell-voikko Cleaning up. ------------ for i in $(dpkg -l|grep ^rc|cut -d' ' -f3);do dpkg -P $i;done Check if the upgraded system works. ----------------------------------- Reboot and test if it works like before: Log in as first user and test if the GOsa² gui is working, if you're able to connect LTSP clients and workstations, if you can add/remove a netgroup membership of a system, if you can send and receive internal email, if you can manage printers and maybe other site specific things. Use the testsuite scripts if you spot an error. ==================================================================== Update LTSP chroot (default arch i386) as root. ----------------------------------------------- sed -i '/jessie/ s/deb/#deb/g' /opt/ltsp/i386/etc/apt/sources.list ltsp-chroot -m apt-get update ltsp-chroot -m apt-get -y upgrade sed -i 's/wheezy/jessie/g' /opt/ltsp/i386/etc/apt/sources.list ltsp-chroot -m apt-get update ltsp-chroot -m apt-get -y dist-upgrade ltsp-chroot -m apt-get -f install ltsp-chroot -m apt-get -y dist-upgrade (Repeat the last two commands if dpkg still errors out.)
