But whatever the bug, why saving in the package-cache?
The package-cache is just a cache as the name tells.
It's less volatile than RAM, but can still be subject to aggressive cleanup.

Hi vincent

Welcome to Pharo.
- Did you check that you can write in your cache folder?
- Is there any files in your cache?
- Normally just selecting a package and pressing save should save it.
- The exception you report is super strange.
