Comment 1 for bug 1535556

Thank you for sending your problem.

We think that the problem is not on your computer or its system configuration, but on the cube server itself. There is a package in your list of upgradable packages that cube can't handle, maybe because of lots of package dependencies it requires.

For now, you may try to mark some upgradable packages and download them instead of marking and downloading all upgradable packages.

Could you attach your cube project here? Please compress it to .zip to lessen the size. This will help us in our investigation.

Sorry for inconvenience and we will try our best to fix the problem.
