我有 Ubuntu 22.04 LTS（从 20.04 LTS 升级而来）。看来我的内核没有自动升级到较新的次要版本：
root:~# dpkg uname -a
Linux destop 5.15.0-47-generic #51-Ubuntu SMP Thu Aug 11 07:51:15 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
root:~# dpkg -l | grep linux-image
ii linux-image-5.15.0-47-generic 5.15.0-47.51 amd64 Signed kernel image generic
rc linux-image-unsigned-5.11.0-25-generic 5.11.0-25.27~20.04.1 amd64 Linux kernel image for version 5.11.0 on 64 bit x86 SMP
虽然有更新的版本已回购（5.15.0-48） 我也可以找到它：
root:~# apt search linux-image-5.15.0-48
Sorting... Done
Full Text Search... Done
linux-image-5.15.0-48-generic/jammy-updates,jammy-security 5.15.0-48.54 amd64
Signed kernel image generic
linux-image-5.15.0-48-lowlatency/jammy-updates,jammy-security 5.15.0-48.54 amd64
Signed kernel image lowlatency
我不想升级到较新的版本（例如 5.19），只想升级次要版本。我只是假设标准
apt update && apt ugprade会自动升级内核。我的假设错了吗？还是我的系统配置有误？谢谢
