Comment 1 for bug 1673842

Hello and thank you for sending your problem.

This problem will most likely occur if apt-get detects that there are still packages that needs to be downloaded (this also includes the recommended packages for that application). It will automatically close, and it seems that cube-server was not able to display the error to you.

dpkg, unlike apt-get, is less strict, and will allow installation if the downloaded packages are enough to install your application.

You can check the installation logs in this file. Please send the output also to us to help you more in this issue.

Sorry for the inconvenience, and we will try our best to fix the issue.
Thank you also for the feedback :) Much appreciated!
