Is your /tmp in tmpfs? (default in trixie)
If yes, can you disable it and try without it?
I've built the package with autopkgtest-virt-qemu like this:
$ autopkgtest --shell -U . -- qemu -c8 /tmp/unstable.img

You can now log into the VM through the serial terminal.
Depending on which terminal program you have installed, you can use one
of
ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -p
10022 user@localhost
minicom -D unix#/tmp/autopkgtest-qemu.5pka1e2x/ttyS0
nc -U /tmp/autopkgtest-qemu.5pka1e2x/ttyS0
socat - UNIX-CONNECT:/tmp/autopkgtest-qemu.5pka1e2x/ttyS0
The tested source package is in
/tmp/autopkgtest.kaN4jw/build.GVu/real-tree
Now in that virtual machine, I've confirmed that no tmpfs is involved:
