you could preseed your installer to install the kernel in the PPA. I have not tested the instructions below.. but should give you an idea how to preseed. From your comment above looks like you might not have a booting system to be able to install the new kernel etc.
Assuming you are using a netboot install. -- tell installer grub to use preseed -- Edit ubuntu-installer/ppc64el/grub/grub.cfg and add your preseed file. Like for example: menuentry 'Install' { set background_color=black linux /ubuntu-installer/ppc64el/linux auto=true priority=critical url=http://<web server>/preseed/preseed.ppc64el --- quiet initrd /ubuntu-installer/ppc64el/initrd.gz } -- preseed example -- You can use late-commands in your preseed file to install the PPA kernel like: # Install kernel from PPA d-i preseed/late_command string in-target add-apt-repository -y ppa:ubuntu-power-triage/lp1770003 d-i preseed/late_command string in-target apt update d-i preseed/late_command string in-target apt install -y linux-image-unsigned-4.15.0-20-generic linux-modules-extra-4.15.0-20-generic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1770003 Title: qla2xxx: Fix page fault at kmem_cache_alloc_node() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1770003/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
