Public bug reported:

I want to get the stap-prep command (part of systemtap package) working
with ubuntu desktop 24.04 x64

I am using ubuntu desktop 24.04.4 on x64, along with gcc 13.

Previously this computer was upgraded-in-place from 22.04 LTS and before
that from 18.04 LTS on bare metal.

I installed systemtap by following the (somewhat out of date):
https://sourceware.org/systemtap/wiki/SystemtapOnUbuntu
and also 
https://wiki.ubuntu.com/Kernel/Systemtap

I run stap-prep to ensure kernel-headers, debug-symbols and build-tools 
matching my current kernel are installed.
But instead all I get is an error message as below:

# stap-prep
Configuring for kernel release 6.8.0-124-generic
Please wait, attempting to download /lib/modules/6.8.0-124-generic/vmlinuz 
debuginfo
Increasing DEBUGINFOD_TIMEOUT to 300 temporarily
Cannot open /lib/modules/6.8.0-124-generic/vmlinuz: No such file or directory
Server query failed: Invalid argument
Download failed.
