I did Alpine upgrade from 3.19.x to 3.20.2 in my physical server using
an upgrade shell script.

Repositories under /etc/apk dir =
http://dl-4.alpinelinux.org/alpine/v3.19/main
http://dl-4.alpinelinux.org/alpine/v3.19/community
https://dl-cdn.alpinelinux.org/alpine/v3.20/main/
https://dl-cdn.alpinelinux.org/alpine/v3.20/community/

After upgrade, I see following messages at end =

If I do cat /etc/os-release =
NAME="Alpine Linux"
ID=alpine
VERSION_ID=3.20.2
PRETTY_NAME="Alpine Linux v3.20"
HOME_URL="https://alpinelinux.org/"
BUG_REPORT_URL="https://gitlab.alpinelinux.org/alpine/aports/-/issues"

output / ls of /lib/modules = 4.19.176-0-vanilla

I am now worried if the OS fails to boot after the restart/reboot.
Any thoughts if I can ignore that warning and reboot the server?
The OS has been upgraded to 3.19 version earlier from older versions.

Regards,
Amey.

Kernel you are using was removed 5 years ago
https://git.alpinelinux.org/aports/commit/?id=eba4f554cc5

1. remove all repos from /etc/apk/repositories, except 3.20 ones.
2. apk update
3. apk upgrade --available --simulate
4. carefully check what packages are missing and what needs reinstalling
5. install linux-lts and whatever else
6. check that bootloader picked up new kernel

Hello Konstantin,

Thank you very much for your input.

I think I'll update all packages as all of them look essential packages.

> 5. install linux-lts and whatever else
May I know how can I do that? Thanks.

> 6. check that bootloader picked up new kernel
Yes will do.
