Excellent,
we were referring to https://wiki.ubuntu.com/Kernel/CrashdumpRecipe
which has obsolete keys?
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys ECDCAD72428D7C0 ??

With https://wiki.ubuntu.com/Debug%20Symbol%20Packages we are able to
install linux-image-4.15.0-11-generic-dbgsym ppc64el 4.15.0-11.12

With regards,
Naveed

This question is odd. How do you normally "get dbgsym" packages and
install them?

Have you followed the instructions at
https://wiki.ubuntu.com/Debug%20Symbol%20Packages to enable the debug
symbols repository, and thus have all -dbgsym packages available for
installation with "apt install" for any package in Ubuntu?

Sorry for the noise,

I verified this now,
=
# dpkg -s crash
Package: crash
Status: install ok installed
Priority: optional
Section: utils
Installed-Size: 10698
Maintainer: Ubuntu Developers 
Architecture: ppc64el
Version: 7.2.1-1
Depends: libc6 (>= 2.17), liblzo2-2, libncurses5 (>= 6), libsnappy1v5, 
libtinfo5 (>= 6), zlib1g (>= 1:1.2.0), binutils
Suggests: kexec-tools, makedumpfile
Description: kernel debugging utility, allowing gdb like syntax
The core analysis suite is a self-contained tool that can be used to
investigate either live systems, or multiple different core dump formats
including kdump, LKCD, netdump and diskdump.
.
o  The tool is loosely based on the SVR4 crash command, but has been
completely integrated with gdb in order to be able to display
formatted kernel data structures, disassemble source code, etc.
.
o  The current set of available commands consist of common kernel core
analysis tools such as a context-specific stack traces, source code
disassembly, kernel variable displays, memory display, dumps of
linked-lists, etc.  In addition, any gdb command may be entered,
which in turn will be passed onto the gdb module for execution.
.
o  There are several commands that delve deeper into specific kernel
subsystems, which also serve as templates for kernel developers
to create new commands for analysis of a specific area of interest.
Adding a new command is a simple affair, and a quick recompile
adds it to the command menu.
.
o  The intent is to make the tool independent of Linux version dependencies,
building in recognition of major kernel code changes so as to adapt to
new kernel versions, while maintaining backwards compatibility.

On Ubuntu 1804 Bionic, with 4.15.0-10 kernel. crash analysis failed. I think

Repeating the same question about the 4.13.0-25-generic kernel debug symbols:

I was also not able to find this debug symbol for 18.04 kernel. I
understand that the current 18.04 kernel is old and was removed from the
archive. Is it correct?
