Actual Results

fatal: [s1]: FAILED! => {"changed": false, "cmd": "/usr/sbin/update-kernel -y", "msg": "ATTENTION: Your APT database is 7 days old, please run 'apt-get update'!\nupdate-kernel: There are no available kernels with kernel flavour un-def", "rc": 1, "stderr": "ATTENTION: Your APT database is 7 days old, please run 'apt-get update'!\nupdate-kernel: There are no available kernels with kernel flavour un-def\n", "stderr_lines": ["ATTENTION: Your APT database is 7 days old, please run 'apt-get update'!", "update-kernel: There are no available kernels with kernel flavour un-def"], "stdout": "Running kernel: kernel-image-un-def-6.1.131-alt0.c10f.2\nChecking for available un-def kernel packages...\n", "stdout_lines": ["Running kernel: kernel-image-un-def-6.1.131-alt0.c10f.2", "Checking for available un-def kernel packages..."]}

Some points:

1. Return code 1 is OK when new kernel is not available:

[root@s1 ~]# /usr/sbin/update-kernel -y
ATTENTION: Your APT database is 7 days old, please run 'apt-get update'!
Running kernel: kernel-image-un-def-6.1.131-alt0.c10f.2
Checking for available un-def kernel packages...
update-kernel: There are no available kernels with kernel flavour un-def
[root@s1 ~]# echo $?
1

2. Message "Try to install new kernel" is not shown when there is no new kernel:

[root@s1 ~]# /usr/sbin/update-kernel -y
ATTENTION: Your APT database is 7 days old, please run 'apt-get update'!
Running kernel: kernel-image-un-def-6.1.131-alt0.c10f.2
Checking for available un-def kernel packages...
update-kernel: There are no available kernels with kernel flavour un-def
