Package: autopkgtest Version: 5.19 Severity: normal It looks as if one of the necessary consoles is not set up properly on armhf (it worked fine for me on arm64):
$ sudo autopkgtest-build-qemu \ --architecture armhf \ --mirror http://deb.debian.org/debian \ unstable armhf.img ... $ autopkgtest libocas -- qemu \ --dpkg-architecture armhf \ -d --show-boot \ armhf.img produces | host login: autopkgtest-virt-qemu: DBG: expect: found "'login prompt on serial console'" | autopkgtest-virt-qemu: DBG: expect: b'ok' | autopkgtest-virt-qemu: DBG: setup_shell(): no default shell on hvc1 or ttyS1 | qemu-system-arm: terminating on signal 15 from pid 1316826 (/usr/bin/python3) | autopkgtest-virt-qemu: DBG: cleanup... | <VirtSubproc>: failure: The VM does not start a root shell on ttyS1 or hvc1 already. The only other supported login mechanism is through --user and --password on the guest ttyS0 [By the way, libocas is just a tiny library with no dependencies that I tend to use as a smoke test.] Best, Christian
