Comment 5 for bug 1435324

Well, I don't know if the duplicate status is wrong or not. But I am meeting the same problem. The duplicate bug said the fix was released in the -updates repo, but my problem is not fixed until now. I did "sudo apt-get dist-upgrade" to the latest release. I can not install qt5-default and the following is the errors:

$ sudo apt-get install qt5-default
