Learn more about how to get the fixes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well. The problem can be corrected by updating your system to the following package versions: Ubuntu Release Package Version 24.04 LTS noble linux-image-6.8.0-1052-azure – 6.8.0-1052.58 linux-image-azure-6.8 – 6.8.0-1052.58 linux-image-azure-lts-24.04 – 6.8.0-1052.58 22.04 LTS jammy linux-image-6.8.0-1052-azure – 6.8.0-1052.58~22.04.1 linux-image-azure – 6.8.0-1052.58~22.04.1 linux-image-azure-6.8 – 6.8.0-1052.58~22.04.1 Reduce your security exposure Ubuntu Pro provides ten-year security coverage to 25,000+ packages in Main and Universe repositories, and it is free for up to five machines.
