Hi.
I have performed the update on a Pcengines APU2 and it went perfect. The only thing, during the update, has given me the following error:
But hitting INTRO, you have returned to Pakfire and done it correctly.

Now it’s time to test it to see if I detect a problem, but for now, good.
Thanks developers !!!. 
After running OK for a few days, I encountered a network error:
/var/ipfire/ethernet/settings was identical, save different static IP for red0, to different instance running core 153
In the process, I discovered that the backup does not contain “/var/ipfire/ethernet/settings” which would be useful for restoring a minimally configured new installation to previous settings.
I rebooted from a minimally configured core 153 and copied “/var/ipfire/ethernet/settings” across to core 154. Core 154 now generally working, but I still can’t browse to the gateway, which is the only way of configuring it.
I did an update of a working x86 core 153 stable OVM instance and now the red interface is not working anymore, maybe due to the “Bad system call” on startup? - see screenshot.
All testers: There’s a new build of Core154 available (commit 896fa74d, as of 2021-02-16 19:00).
Does the new build address the dhcp-fail? Anyway, how to fetch it? It is not offered as Available update by Pakfire in Repository “Testing”, and the “Unstable” repo delivers a core 155 build.
If you’ve already switched to the “Testing” repo and upgraded to 154, you’ll have to edit the file
/opt/pakfire/db/core/mine
and change “154” to “153” so that you’ll be offered the latest Testing build.
The change log can be viewed in a browser at:

That worked just fine, easy. And dhcp client does work again:
