Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS: linux-image-5.4.0-1046-ibm 5.4.0-1046.51~18.04.1 linux-image-5.4.0-1082-raspi 5.4.0-1082.93~18.04.1 linux-image-5.4.0-1098-oracle 5.4.0-1098.107~18.04.1 linux-image-5.4.0-1099-aws 5.4.0-1099.107~18.04.1 linux-image-5.4.0-1102-gcp 5.4.0-1102.111~18.04.2 linux-image-5.4.0-1105-azure 5.4.0-1105.111~18.04.1 linux-image-5.4.0-146-generic 5.4.0-146.163~18.04.1 linux-image-5.4.0-146-generic-lpae 5.4.0-146.163~18.04.1 linux-image-5.4.0-146-lowlatency 5.4.0-146.163~18.04.1 linux-image-aws 5.4.0.1099.77 linux-image-azure 5.4.0.1105.78 linux-image-gcp 5.4.0.1102.78 linux-image-generic-hwe-18.04 5.4.0.146.163~18.04.117 linux-image-generic-lpae-hwe-18.04 5.4.0.146.163~18.04.117 linux-image-ibm 5.4.0.1046.57 linux-image-lowlatency-hwe-18.04 5.4.0.146.163~18.04.117 linux-image-oem 5.4.0.146.163~18.04.117 linux-image-oem-osp1 5.4.0.146.163~18.04.117 linux-image-oracle 5.4.0.1098.107~18.04.70 linux-image-raspi-hwe-18.04 5.4.0.1082.79 linux-image-snapdragon-hwe-18.04 5.4.0.146.163~18.04.117 linux-image-virtual-hwe-18.04 5.4.0.146.163~18.04.117 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.
