Update (posted on slack):

I found the cause (albeit not root cause) of the report.toml permissions denied issue on pack-orb. It’s essentially the same as this report from RHEL where the default installed version of docker is old. In this case the default machine circleci offers is using Ubuntu 14.04.5 LTS with docker 17.09.0-ce. Changing the machine option to ubuntu-2004:202010-01 then uses Ubuntu 20.04.1 LTS with docker 19.03.13 resolves the issue. It may be worth investigating further but for pack-orb this seems like it would be sufficient to move forward.

Here are some relevant logs:

• debug showing default docker info, pack/build showing report.toml error
• debug showing working docker info, build showing successful build
