Qlustar 14, cannot use lustre-2.15 module
by Rolandas Naujikas 12 Aug '26

12 Aug '26

Hi, The following packages have unmet dependencies: qlustar-module-lustre-2.15-noble-amd64-14 : Depends: qlustar-module-core-noble-amd64-14 (= 14.0.5-b589f1605) but 14.1.9-b589f1641 is to be installed So I forced to use lustre-2.17, but I would like to update first from Qlustar 13 with lustre-2.15 to the same version of Lustre, so I could go back in case of problems. Regards Rolandas

Security/Bug fix release 14.1.6
by no-reply-list＠qlustar.org 22 Jul '26

22 Jul '26

The Qlustar release 14.1.6 is ready including a number of security/bug fixes. Please check the following web pages for details about security fixes and special update instructions: https://qlustar.com/qsa/2026/0721261 https://qlustar.com/qsa/2026/0721262 Please note: Due to the increased threat level by the high frequency of discovered and exploitable security bugs, we are now shortening our usual security update release cycle and will couple it mostly to newly released kernel.org kernel versions. Since the kernel.org update frequency of the Qlustar 13 kernel 5.15.x is a lot less than that for the 6.12.x Qlustar 14 kernel, this means that we will also have security releases covering only Qlustar 14. This is an example. No non-security related updates/enhancements/bug fixes are included.

Stange Qluman quirks
by João Rodrigues 21 Jul '26

21 Jul '26

I recently upgraded our cluster from Qlustar 13 to 14. Since yesterday I noticed strange behaviors in Qluman GUI: 1. When using Hardware or GPU wizards, no nodes are shown in the "selected" list, even though I selected one in the "Enclosure view" window. 2. On the "Slurm Config" window, when creating a new "Gres group", I select a Type of GPU, but when pressing enter or tab, it is cleared. 3. Today, the "Enclosure view" is completely blank. Since I noticed these problems yesterday, I have avoided writing changes to files. What could be causing this? João Rodrigues

Security/Bug fix release 14.1.5.1
by no-reply-list＠qlustar.org 14 Jul '26

14 Jul '26

The Qlustar release 14.1.5.1 is ready including a number of security/bug fixes. Please check the following web pages for details about security fixes and special update instructions: https://qlustar.com/qsa/2026/0714261 This update includes several security related package updates from AlmaLinux only. In particular it includes fixes for the two critical kernel bugs GhostLock CVE-2026-43499) and Januscape (CVE-2026-53359). Note that Qlustar 14/Ubuntu already received fixes for both of these with the release 14.1.5 from July 4th. Important: The Qlustar 13 kernel 5.15.x is still vulnerable to both GhostLock and Januscape. It seems kernel developers are heavily overloaded and have decided to focus on the most recent LTS kernels for security fixes. In the light of this, we highly recommend to update Qlustar 13 systems to Qlustar 14 as soon as possible. Nevertheless, we will provide patched Qlustar 13 kernels as soon as they are available from upstream.

Addendum for Security/Bug fix releases 14.1.5, 13.4.5
by no-reply-list＠qlustar.org 09 Jul '26

09 Jul '26

This is an addendum to our release notes for Qlustar releases 14.1.5 and 13.4.5 which were published on Saturday. Since then a few local root exploits and other critical bugs have been published, in particular - GhostLock (CVE-2026-43499) - Bad Epoll (CVE-2026-46242) - Januscape (CVE-2026-53359) Qlustar 14.1.5/Ubuntu has fixed all of these bugs and you are urged to update your systems if you haven't done so. Qlustar 14.1.5/Alma and Qlustar 13.4.5 are not vulnerable to Bad Epoll, but are still vulnerable to Januscape and GhostLock. In general we highly recommend to update to Qlustar 14 if you haven't done so yet, as the Qlustar 13 kernel 5.15.x receives fixes by upstream with a much larger delay as compared to the Qlustar 14 kernel 6.12.x.
