Comment 4 for bug 2056662

Finally after hitting Cancel on the "Open a browser in terminal" option (since I already filed the bug report in my desktop browser), I get the following message/errors:

The upgrade has aborted. Your system could be in an unusable state. A
recovery will run now (dpkg --configure -a).
