Update instructions

After a standard system update you need to reboot your computer to make all the necessary changes.

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
20.04 LTS focal linux-image-5.15.0-1057-nvidia-tegra –  5.15.0-1057.57~20.04.1  
linux-image-5.15.0-1057-nvidia-tegra-rt –  5.15.0-1057.57~20.04.1  
linux-image-nvidia-tegra –  5.15.0.1057.57~20.04.1  
linux-image-nvidia-tegra-5.15 –  5.15.0.1057.57~20.04.1  
linux-image-nvidia-tegra-rt –  5.15.0.1057.57~20.04.1  
linux-image-nvidia-tegra-rt-5.15 –  5.15.0.1057.57~20.04.1
