Weekly Changes – 15/04/2024

Not much change this week, mainly just preparatory work for upgrading to a new kernel on Ubuntu. Here are the details of all the notable changes…

Ubuntu Kernels

The Jammy HWE kernel is updated to the 6.5 series from the 6.2 series.

The Focal and Jammy INF_TEST kernel has been updated to 5.15.0-102.112 and standard kernels are also updated to the latest available from Ubuntu.

NVidia Packages

The nvidia package lists for Ubuntu are now generated by a new script which should help keep everything up to date more easily. Given the big change in how the file is managed there is a small risk that problems may have been introduced, please test this thoroughly and let us know how you get on.

Ubuntu Jammy sees support for the 6.5.0 series added and for the 6.2.0 series dropped.

Default ED GRUB Password

A default password is now set in ed/options/ed-site.h which protects the GRUB menu installed on the hard disk, preventing unauthorised editing of entries and arbitrary booting. This password is applied to the root GRUB user.


A bug in the LCFG nagios server code was discovered that meant if any of the contacts for a host or service were invalid the whole list would be ignored. This has only been fixed for Ubuntu as we expect to drop support for SL7 fairly soon.

Changes to headers and package lists

Members of the Informatics Computing team can browse all the changes to the headers and package lists.
