Two Fedora VMware Guests - one with a specific problem ...
by Walter H. 10 Jul '26

10 Jul '26

Hello, I have two VMware guests running latest Fedora Fedora 44 - both LXDE one with bridged LAN adapter and one with VMware NAT LAN adapter, means this can only be reached from the host itself, but can use internet like my host behind a NAT router itself the one with the bridged LAN adapter has the specific problem: I can't copy & paste between host and guest; I know that this has worked without any problems several time ago; where do I have to look to find the cause about this? is it somewhere at the VMware itself? Thanks, Walter H.

vulnerabilities.
by home user 09 Jul '26

09 Jul '26

Within the past few days, I saw an article in Yahoo Finance or Yahoo News reporting that some AI (Anthropic) finds thousands of security vulnerabilities in every major operating system and browser. Here's one article about this: "https://thehackernews.com/2026/04/anthropics-claude-mythos-finds.html", but I don't know if that's the same article that I saw before. I wonder: just how vulnerable is Fedora? ... and how vulnerable is Firefox?

OT: EC and Kernel module conflict
by Dr. Tibor Attila Anca 07 Jul '26

07 Jul '26

Hi, This is OT, because not Fedora, but Kernel specific. It might however ring some bells... I am using an X1 Carbon 9th generation with Fedora 44. It is a known problem, that the embedded controller and the kernel acpi modules of kernel 7.* have a conflict which results in false rpms on fan 1 (65535) and ultimately lets both fans to work with max. rpm, even if the cpu deep freezes. My solution was (after days of tinkering with acpi fan control, watchdog, thinkfan, etc., to pull the 6.17.1 Kernel of f43, set it default and prevent dnf to do anything with it. Sensors is now delivering correct values. Did anyone else have this problem? Did anyone else succeed to solve it by staying with kernel 7.1? An official patch should come in August and make it into kernel 7.2 or so, but till than my fans would be twice around the world... Thanks and regards Tibor

Install inxi and post `inxi -Fzxx` output here. The basics of debugging on Fedora is to look in the user and system journals. In your case you are, it seems, that gdm is the of immediate interest. What is the status of the gdm service `systemctl status gdm.service`? Barry P.S. Your email setting make reading your emails challenging in dark mode.

dnf system-upgrade to Fedora 44 - no .rpmnew for changed configuration files!?
by Franta Hanzlík 07 Jul '26

07 Jul '26

I upgraded Fedora 38 to Fedora 44 (assuming 44-38≅2 ;), and now I'm going through /etc/ and fixing config files for services that aren't working. And I'm unpleasantly surprised that the upgrade didn't create any versions of the config files included in the packages, which would normally be written as .rpmnew files. For example, I'm currently editing the configuration of NUT (Network UPS Tool) - it has a lot of config files in /etc/ups/, I had most of them changed in Fedora 38, after the upgrade to 44 they remained unchanged - but there is not a single .rpmnew/.rpmold file. Which is annoying, because this piece of SW has apparently been evolving quite a bit lately - e.g. the default configuration file, which was 5 kB in F38, is now 12 kB, etc. So if I wanted to edit the configuration on new versions of the files, I would have to download them additionally - which is extra work. Is this behavior of the package upgrade normal and logical? -- Thanks, Franta Hanzlik

So I did an unguaranteed ;) upgrade 38 -> 44, almost standard procedure, only at the beginning I copied the keys for Fedora 42-44 to /etc/pki/rpm-gpg/ (the keys up to F41 were already there). And then the classic: - dnf system-upgrade download --releasever=44 (here I verified that there was no package collision) - dnf system-upgrade reboot which went well, the upgrade to Fedora 44 was performed and almost everything worked correctly. I only manually configured the network for NetworkManager (there were old network-scripts on F38). But would upgrading more than two versions cause the .rpmnew version of the configuration files to be missing? I know that the guaranteed upgrade of Fedora is at most two versions higher (that's why I wrote "44-38≅2"). So I did a non-guaranteed upgrade 38 -> 44, using the standard procedure from fully-updated Fedora 38: dnf system-upgrade download --releasever=44 dnf system-upgrade reboot --

Is anyone interested in testing pre-built kernel modules? (NVIDIA, first)
by Gordon Messmer 06 Jul '26

06 Jul '26

Hi, I'm a Fedora package maintainer with an SRE background. As an SRE, I believe that the current common practice of building kernel modules from source on the system where they will be used is inherently unreliable, and we can do better. I've built a workflow that automatically rebuilds kernel module packages when Fedora's maintainers submit a new kernel package for testing. The build process operates in a secure AWS VPC, and uses KMS to sign modules and packages with keys that can't be exfiltrated. There are rough spots for third party kernel module packages, but I think I'm at a point were I can start inviting users to help by testing the packages and reporting any problems. The first module I'm building is NVIDIA's open kernel module, but other modules may be offered in the future. Documentation for the installation process is here: https://project-resistor.codeberg.page/2026/07/05/installing-nvidia-kernel-… <https://project-resistor.codeberg.page/2026/07/05/installing-nvidia-kernel-…> And interested users can subscribe to this "issue" and provide feedback: https://codeberg.org/project-resistor-kernel/nvidia-open-kmod/issues/1 <https://codeberg.org/project-resistor-kernel/nvidia-open-kmod/issues/1>
