Comment 1 for bug 2054369

I can reproduce this in an armhf container on an arm64 host.

With python3.11, it works. With python 3.12, it doesn't. We should be able to narrow this down now.

root@n-armhf:~# python3.12 ./wait-for-apt-update-to-finish
lockdata = b'\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00'
