One possibility is that the repository list might be incorrect after
the upgrade. Would you mind posting the content of the following file:
>From the Lubuntu system which you have trouble with?
Another possibility I can think of is the repository cache might be
corrupted. Please try the following commands:
$> sudo apt-get clean
$> sudo apt-get update
$> sudo apt-get check
And if they all run successfully, try and see if you can install "qjackctl" now.
