Avocado error fetching QEMU boot_linux.py assets

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

Hi,

[cross list post]

Using QEMU at commit 3cbc8970f5 I'm getting this error:

Fetching assets from tests/acceptance/boot_linux_console.py.
Fetching assets from tests/acceptance/boot_linux.py.

Same if I revert these:
0f26d94ec9 ("tests/acceptance: skip s390x_ccw_vrtio_tcg on GitLab")
1c80c87c8c ("tests/acceptance: refactor boot_linux to allow code reuse")

If I remove boot_linux.py, all other files are processed correctly.

Any idea what can be wrong here?

Thanks,

Phil.
