Many times I tried to load packages with AppCafe; it worked for Firefox and Thunderbird but recently not for KDE (begun but seemed to be stopped for 2 hours while loading the doc) and LibreOffice.
LibreOffice was in the file after KDE.
I stopped AppCafe and after KDE disappeared from “pending” and "install and LibreOffice is still pending but I see no mean to make him start !!!
I wonder how to do !
