Hello @mbergal. Thank you for your report. It looks like a user or tool on your self-hosted runner does not have permissions to write in /home/ubuntu/.npm/_cacache. Could you please run your job under the user with appropriate permissions.

The setup-node action uses toolkit/cache to save/restore cache. You can try to find similar issue in the toolkit or actions/cache repositories.

The command in question /usr/bin/tar -z -xf cache.tgz -P -C /data/actions-runner/_work/ai-general/ai-general is trying to create something not in /home/ubuntu/.npm/_cacache, but in /data. Is it expected?

Hello @mbergal. Thank you for your response. For getting directory for cache we use the npm config get cache command. Do you change user or override cache directory (npm config set cache) ?

Hello @mbergal. Do you have any updates or additional information ?

Hello @mbergal. I'm going to close the issue. We've tried to reproduce from our side, but it works as expected. If you get any additional information or repro steps feel free to ping us.
