  * Update {{{/etc/apt/sources.list}}} and individual configurations in {{{/etc/apt/sources.list.d/}}}, so that packages for Debian wheezy will get installed with next upgrade / dist-upgrade.
  * Run upgrade and dist-upgrade in two steps{{{

  * Reboot into the new Debian wheezy system, ignore if some services are broken / non-functional.

  * Don't forget the reboot into the Debian wheezy system, because you will run into troubles when upgrading the {{{udev}}} package from wheezy to jessie.

== Fixing the TJENER setup after package upgrade ==

The Debian Edu mainserver is not easily upgradable, because the mainserver installation process in Debian Edu does many modifications to the plain Debian system.

=== Fix DNS server (bind9) ===

During the upgrade process, the DNS server configuration (synced into text files from LDAP) gets lost. You need to rebuild the DNS server configuration files from LDAP manually.

Fixing the TJENER setup after package upgrade

The Debian Edu mainserver is not easily upgradable, because the mainserver installation process in Debian Edu does many modifications to the plain Debian system.

Fix DNS server (bind9)

During the upgrade process, the DNS server configuration (synced into text files from LDAP) gets lost. You need to rebuild the DNS server configuration files from LDAP manually.

  • Add

    10.0.2.2 ldap.intern
    to /etc/hosts temporarily.

  • Add

    BIND_DATA="/etc/bind"

    at the end of /etc/default/ldap2zone.

  • Rebuild the DNS configuration (in /etc/bind) via ldap2bind command:
