I am an ICT professional with over 30 years of experience. My company has many installations of Ubuntu 24.04 Desktop running, all updated, all the same. 3 of them are running with AMD proprietary video driver installed. 3 of them are Laptops, one is Desktop, one Intel NUC. All of them are set on the same sources.
As of yesterday, 1 of them has upgraded to Kernel 6.11, while the other 4 were not showing it. Exactly the same packaged sources. The earliest one who did the upgrade (a Laptop with AMD) completely broken the system, as DKMS of AMD failed to compile. Today another one (my own Laptop) is showing the update which would break the system. I have not done it. The Desktop is not showing the update, nor is the NUC and nor is another Laptop.
Why is the logic in which APT understands if there are new packages to be installed, from the same sources, different for the same OS ? I am totally confused.
I have even changed the Desktop to the main source of packages, thinking a mirror maybe not synced very well, and apt is still refusing to show the Kernel upgrade.
An explanation as to what is going on would be nice.
Thank you, Best Regards, Simone
