Comment 11 for bug 1928075

Testing by trying to execute /sbin/ldconfig within the aarch64 Debian bullseye chroot on 20.04 amd64 host for all installed kernels is working, including 5.12.0, the version booted to by default !

That is: 5.4.0-73-lowlatency 5.8.0-41-lowlatency 5.10.2 5.11.0+ 5.12.0-elloe+

This is extremely difficult to understand since I only got involved in reproducing and testing this on my PC when my colleague hit this issue (recall his PC is on v5.10.0).

Now, using qemu-debootstrap to build a new Debian bullseye also works (remembering to set ownership on the directory to root first!).

Seemingly now working - so now I am extremely confused :s

I'll retest on my colleagues PC tomorrow !
