It is also impossible to install packages using apt-get program. I tried stellarium, geogebra and avolution.
See attachment.

Hi again,

unfortunally I am not able to reproduce this.

On my live system run with edubuntu current/daily the install button is there.

Wee, I have given 2GB memory to the live system, when you use a low memory system this may be the cause for no installation abilities.

The last screenshot of the terminal output may be of interest.

Unfortunally I can not read Italiano.

Can you reproduce with a english live system run and attach a new screenshot with the english output here?

 I have seen that you have subscribed here. Can you translate or doing the triaging when you are just online?

It looks to me like dvd.listlangpack has an invalid extension for a sources.list file. It should probably have a .list extension.

Tried with today's image, /etc/apt/sources.list is valid, the dvd list file is called /etc/apt/sources.list.d/dvd.list so is also valid, /var/lib/apt/lists contains the required package lists. apt-cache, apt-get and software-center work out of the box in the live environment.

Marking the bug Invalid.
