Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS: linux-image-5.4.0-1025-gkeop 5.4.0-1025.26 linux-image-5.4.0-1045-raspi 5.4.0-1045.49 linux-image-5.4.0-1054-gke 5.4.0-1054.57 linux-image-5.4.0-1056-oracle 5.4.0-1056.60 linux-image-5.4.0-1058-aws 5.4.0-1058.61 linux-image-5.4.0-1062-azure 5.4.0-1062.65 linux-image-aws-lts-20.04 5.4.0.1058.61 linux-image-azure-lts-20.04 5.4.0.1062.60 linux-image-gke 5.4.0.1054.64 linux-image-gke-5.4 5.4.0.1054.64 linux-image-gkeop 5.4.0.1025.28 linux-image-gkeop-5.4 5.4.0.1025.28 linux-image-oracle-lts-20.04 5.4.0.1056.56 linux-image-raspi 5.4.0.1045.80 linux-image-raspi2 5.4.0.1045.80 Ubuntu 18.04 LTS: linux-image-5.4.0-1025-gkeop 5.4.0-1025.26~18.04.1 linux-image-5.4.0-1045-raspi 5.4.0-1045.49~18.04.1 linux-image-5.4.0-1054-gke 5.4.0-1054.57~18.04.1 linux-image-5.4.0-1056-oracle 5.4.0-1056.60~18.04.1 linux-image-5.4.0-1058-aws 5.4.0-1058.61~18.04.3 linux-image-5.4.0-1062-azure 5.4.0-1062.65~18.04.1 linux-image-aws 5.4.0.1058.41 linux-image-azure 5.4.0.1062.42 linux-image-gke-5.4 5.4.0.1054.57~18.04.19 linux-image-gkeop-5.4 5.4.0.1025.26~18.04.26 linux-image-oracle 5.4.0.1056.60~18.04.36 linux-image-raspi-hwe-18.04 5.4.0.1045.48 After a standard system update you need to reboot your computer to make all the necessary changes. 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.
