Comment 3 for bug 1801364

Robert,
Can you please attach logs?

cloud-init collect-logs

The 'persist_instance_data' in DataSource tries to accomodate for this.

it uses util.json_dumps which uses json_serialize_default.

Here is an example:

$ python3 -c 'from cloudinit import util; print(util.json_dumps({"bin": open("/dev/urandom", "rb").read(8)}))'
{
 "bin": "ci-b64:doWuT19jT3g="
}

Notice that the dump adds 'ci-b64' in front of the value.

I'm guessing that there is a differnce in python versions that is causing a problem.

Please attach logs.
thanks.
