Weekly Changes – 17/06/2024

This week sees some minor improvements for the installer, here are the details of all notable changes…

Ubuntu installer

The standard Ubuntu installroot profiles now include the UoE keyring so that it is easy to install packages from UoE repositories.

To make the headers clearer, nearly all support for the Ubuntu Focal legacy installer has now been removed.

Currently, it is still necessary to define the USE_NEW_INSTALLER for all Ubuntu profiles but we hope to drop that requirement very soon.


Work is ongoing to provide support for running an NTP service on Ubuntu. There is a new lcfg/options/ntp.h header for including the daemon and the LCFG component on Ubuntu.

For DICE Ubuntu systems there is a new dice/options/ntp-client.h header which was cloned from the existing dice/options/ntp.h. The new name makes it clear that it is specifically intended for NTP client configuration. The change of header also makes it easier to modify for Ubuntu without the risk of breaking old SL7 profiles. By default this will use the Systemd timesyncd, if there’s a requirement to use the NTP daemon instead then it can be enabled using the DICE_OPTIONS_NTP_ENABLE macro.

SASL modules

Following on from its removal from DICE Ubuntu systems last week, the libsasl2-modules-ldap package has been removed from all LCFG profiles. Even when unused, having it installed was causing lots of entries in syslog and logwatch regarding failure to load plugins.

Manual Management of Root’s Password

The ed/options/auth/common/manual-rootpwd.h header has been simplified so that it actually works on Ubuntu where the newer auth component behaves better.
