Comment 7 for bug 2023243

Somehow between bionic/18.04 and focal/20.04 there was not much activity and not a lot of updates on the powerpc-utils package, indeed:
$ rmadison powerpc-utils
 powerpc-utils | 1.2.18+r1.1.3-24ubuntu1 | trusty | source, powerpc, ppc64el
 powerpc-utils | 1.3.1-2 | xenial | source, powerpc, ppc64el
 powerpc-utils | 1.3.1-2ubuntu0.3 | xenial-updates | source, powerpc, ppc64el
 powerpc-utils | 1.3.4-0ubuntu2 | bionic | source, ppc64el
 powerpc-utils | 1.3.4-0ubuntu2 | focal | source, ppc64el
 powerpc-utils | 1.3.9-1ubuntu1 | jammy | source, ppc64el
 powerpc-utils | 1.3.9-1ubuntu2 | kinetic | source, ppc64el
 powerpc-utils | 1.3.10-2 | lunar | source, ppc64el
 powerpc-utils | 1.3.10-2 | mantic | source, ppc64el

We are happy to take requests to upgrade to the latest version, always as part of the current development release (always before Feature Freeze) - and we will consider updating powerpc-utils to latest v1.3.11 for mantic/23.10, the release that is currently in development.
I've now also subscribed myself to GH powerpc-utils for all new tags (releases) to get a notification.

Please notice that there is no P10 support in 20.04 (nor P11) and there will be never support for it - in 20.04, since it would mean that we have to lift the architectural level that we compile for.
That can only be done in the release that is currently in development.
And even trying to install will end up in an illegal instruction error - it's just not compiled for it (except one emulates an older architecture or runs in compat mode - if possible).

For P9 and P10 one actually has to migrate to the latest 22.04 LTS: https://ubuntu.com/download/server/power
20.04 is only still an option in case of P8.

I know that getting the commits to fix something in an older release can be painful, esp. if cherry-picking does not work cleanly and backports are needed - but it's due to the Ubuntu SRU process, that only allows important and critical fixes anyway, so not meant for version bumps, bigger patches or major new features.

We can of course (re-)build the latest version we have in the archive (currently v1.3.10) for focal in a PPA - and that is what I just did: https://launchpad.net/~fheimes/+archive/ubuntu/lp2023243
But this is also not ideal, since this version may for example have support for some P10 hardware features, but the underlying 20.04 has no support for this level - so the door is even more open for further issues one may run into.
So please handle the powerpc-utils package in ppa:fheimes/lp2023243 with care.
