I was aware of this issue but have yet to look further into it. All our other official profiles are just fine, form my test builds a few days ago after releasing 4.0.6 RC 7.
And from you logs this looks very much like a dependency failure in the openSUSE repos for the required dependency of shellinabox. I.e. The repo we are using in this profile has a shellinabox that requires an unavailable version of libc.so.6. At least unavailable from the repos we have specified in that profile.
I’m due to look at this closer soon but wont have time for a but unfortunately. If anyone else could chip in here with attempting to suss what’s gone wrong here and how we can get these upstream dependencies in order that would be great.
So in short it’s a know issue that is not anything to do with what you are doing. I had the exact same error when I machine made (via our buildbot backend) our current private beta ISO images. All the official profiles build just fine except the Pi4 one which is a real shame but it may be that this is resolved in time upstream when the shellinabox is rebuilt against the new libc. But interesting to note is that our Leap15.2.ARM64EFI build just fine a few minutes before I ran into this issue when building the Pi4 installer. So there in may lay the answer, or it may be that things changed upstream between these builds.
I’ll report back here if / when I get time to look to this myself and if anyone else makes any progress on this same issue it would be great to hear about it here.
Thanks again for the report and apologies for my not reporting this myself previously. The recent 4.0.6 release as a big one and took a little more time than I could afford at the time and this missing report was one of the casualties. But we have it here now so that’s great.
