Impossible to run any HTML5 app, even templates in "Ubuntu SDK IDE 4.1.0"

[Aitzol Berasategi]

This error occurs since "Ubuntu SDK IDE 4.1.0" was released. I cannot run any HTML5 app, however any other app, Qml, Scopes,... work well.

When I try to run any html5 template under "Desktop/amd64 Kit" the "Application Output" shows this error:
"bash: /usr/bin/ubuntu-html5-app-launcher: No such file or directory
Application finished with exit code 127.".

When I try to execute under "device-armhf kit" crashes with this error: "desktop:Exec:appname:found unexpected Exec with architecture 'all':./ qtc_device_debughelper.py" and also fires an empty popup with the title "Unknown error".

I have also tried to reinstall the "Ubuntu SDK IDE" following this link: https://developer.ubuntu.com/en/blog/2016/09/07/releasing-410-ubuntu-sdk-ide/ , in a clean install of Ubuntu 16.04.1

Apparantly there is a missing package in the Desktop/amd64 container. To install the missing package follow these steps.
Launch the Ubuntu SDK
Go to Tools->Options->Ubuntu
On the Click Tab (the first one) select the Desktop/amd64 build target.
Click on the Maintain button.
In the terminal window that opens, enter:
~# sudo apt install ubuntu-html5-container
Exit the terminal window
Try running your program again.

Oddly enough this got my program running, but debugging does not seem to work.
