When trying to debug a bug, it's probably best to use the latest Ubuntu kernel version, in case it's already fixed.
Are you specifically looking for older versions of kernels and their dbgsym package? All prior kernel versions can be found here: https://launchpad.net/ubuntu/artful/+source/linux >From that page, select the version. On the next page, select ppc64el under the "Builds" section. The linux-image-VERSION-generic-dbgsym kernel can be downloaded from that last page. ** Changed in: linux (Ubuntu) Status: New => Triaged ** Changed in: linux (Ubuntu) Importance: Undecided => Critical ** Changed in: linux (Ubuntu) Status: Triaged => In Progress ** Changed in: linux (Ubuntu) Assignee: Canonical Kernel Team (canonical-kernel-team) => Joseph Salisbury (jsalisbury) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1744791 Title: [Ubuntu18.04] linux-image-4.13.0-25-generic-dbgsym is not available in repo which is required for crash analysis of vmcore Status in The Ubuntu-power-systems project: Triaged Status in linux package in Ubuntu: In Progress Bug description: ---Problem Description--- No debug kernel deb packages available for 4.13.0-25-generic kernel [Ubuntu 18.04 ] Unable to analyze vmcore generated via crash. ---uname output--- Linux spoon2 4.13.0-25-generic #29-Ubuntu SMP Mon Jan 8 21:15:55 UTC 2018 ppc64le ppc64le ppc64le GNU/Linux Machine Type = 8335-GTC ---Steps to Reproduce--- Install 18.04 ppc64el upgrade kernel to 4.13.0-25-generic or 4.13.0-17-generic try configuring debug repo https://wiki.ubuntu.com/Kernel/CrashdumpRecipe http://ddebs.ubuntu.com/pool/main/l/linux/ sudo tee /etc/apt/sources.list.d/ddebs.list << EOF deb http://ddebs.ubuntu.com/ $(lsb_release -cs) main restricted universe multiverse deb http://ddebs.ubuntu.com/ $(lsb_release -cs)-security main restricted universe multiverse deb http://ddebs.ubuntu.com/ $(lsb_release -cs)-updates main restricted universe multiverse deb http://ddebs.ubuntu.com/ $(lsb_release -cs)-proposed main restricted universe multiverse EOF sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys ECDCAD72428D7C01 sudo apt-get update sudo apt-get install linux-image-$(uname -r)-dbgsym Warning /!\ Be aware that those packages are huge!
