linux-image-5.15.0-134-generic-lpae 5.15.0-134.145
linux-image-5.15.0-134-lowlatency 5.15.0-134.145
linux-image-5.15.0-134-lowlatency-64k 5.15.0-134.145
linux-image-generic 5.15.0.134.133
linux-image-generic-64k 5.15.0.134.133
linux-image-generic-lpae 5.15.0.134.133
linux-image-lowlatency 5.15.0.134.121
linux-image-lowlatency-64k 5.15.0.134.121
linux-image-virtual 5.15.0.134.133

Ubuntu 20.04 LTS
linux-image-5.15.0-134-lowlatency 5.15.0-134.145~20.04.1
linux-image-5.15.0-134-lowlatency-64k 5.15.0-134.145~20.04.1
linux-image-lowlatency-64k-hwe-20.04 5.15.0.134.145~20.04.1
linux-image-lowlatency-hwe-20.04 5.15.0.134.145~20.04.1

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.
