Update Instructions

The problem can be corrected by updating your system to the following package versions: Ubuntu 22.10: linux-image-5.19.0-1015-gcp 5.19.0-1015.16 linux-image-5.19.0-1015-ibm 5.19.0-1015.16 linux-image-5.19.0-1015-oracle 5.19.0-1015.17 linux-image-5.19.0-1016-kvm 5.19.0-1016.17 linux-image-5.19.0-1017-aws 5.19.0-1017.18 linux-image-5.19.0-29-generic 5.19.0-29.30 linux-image-5.19.0-29-generic-64k 5.19.0-29.30 linux-image-5.19.0-29-generic-lpae 5.19.0-29.30 linux-image-aws 5.19.0.1017.14 linux-image-gcp 5.19.0.1015.12 linux-image-generic 5.19.0.29.26 linux-image-generic-64k 5.19.0.29.26 linux-image-generic-lpae 5.19.0.29.26 linux-image-ibm 5.19.0.1015.12 linux-image-kvm 5.19.0.1016.13 linux-image-oem-22.04 5.19.0.29.26 linux-image-oracle 5.19.0.1015.12 linux-image-virtual 5.19.0.29.26 Ubuntu 22.04 LTS: linux-image-5.15.0-1023-ibm 5.15.0-1023.26 linux-image-5.15.0-1023-raspi 5.15.0-1023.25 linux-image-5.15.0-1023-raspi-nolpae 5.15.0-1023.25 linux-image-5.15.0-1026-kvm 5.15.0-1026.31 linux-image-5.15.0-1027-gcp 5.15.0-1027.34 linux-image-5.15.0-1027-oracle 5.15.0-1027.33 linux-image-5.15.0-1028-aws 5.15.0-1028.32 linux-image-5.15.0-1031-azure 5.15.0-1031.38 linux-image-5.15.0-58-generic 5.15.0-58.64 linux-image-5.15.0-58-generic-64k 5.15.0-58.64 linux-image-5.15.0-58-generic-lpae 5.15.0-58.64 linux-image-aws 5.15.0.1028.26 linux-image-aws-lts-22.04 5.15.0.1028.26 linux-image-azure 5.15.0.1031.27 linux-image-azure-lts-22.04 5.15.0.1031.27 linux-image-gcp 5.15.0.1027.22 linux-image-generic 5.15.0.58.56 linux-image-generic-64k 5.15.0.58.56 linux-image-generic-64k-hwe-22.04 5.15.0.58.56 linux-image-generic-hwe-22.04 5.15.0.58.56 linux-image-generic-lpae 5.15.0.58.56 linux-image-generic-lpae-hwe-22.04 5.15.0.58.56 linux-image-ibm 5.15.0.1023.19 linux-image-kvm 5.15.0.1026.22 linux-image-oem-20.04 5.15.0.58.56 linux-image-oracle 5.15.0.1027.22 linux-image-raspi 5.15.0.1023.20 linux-image-raspi-nolpae 5.15.0.1023.20 linux-image-virtual 5.15.0.58.56 linux-image-virtual-hwe-22.04 5.15.0.58.56 Ubuntu 20.04 LTS: linux-image-5.15.0-1027-gcp 5.15.0-1027.34~20.04.1 linux-image-5.15.0-1028-aws 5.15.0-1028.32~20.04.1 linux-image-5.15.0-1031-azure 5.15.0-1031.38~20.04.1 linux-image-5.15.0-58-generic 5.15.0-58.64~20.04.1 linux-image-5.15.0-58-generic-64k 5.15.0-58.64~20.04.1 linux-image-5.15.0-58-generic-lpae 5.15.0-58.64~20.04.1 linux-image-aws 5.15.0.1028.32~20.04.17 linux-image-azure 5.15.0.1031.38~20.04.21 linux-image-gcp 5.15.0.1027.34~20.04.1 linux-image-generic-64k-hwe-20.04 5.15.0.58.64~20.04.24 linux-image-generic-hwe-20.04 5.15.0.58.64~20.04.24 linux-image-generic-lpae-hwe-20.04 5.15.0.58.64~20.04.24 linux-image-virtual-hwe-20.04 5.15.0.58.64~20.04.24 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.
