I am trying to install apps (skype, wine applications, qgis, even suduko) through the software center but i keep getting this boxed message:
"Requires installation of untrusted packages
the action would require the installation of packages from unauthenticated sources"
options in box are:
details, ok, repair
details - tell me i.e. libqtwebkit4 (this was for skype install)
repair - just makes the box disappear for a while, two arrows spin in the top bar next to the word progress ( 1 then 2 ) and it says installing...... then it comes back again with the same message
ok - just stops the install and leaves the message "please install skype via your normal software channels. Only install this file if you trust its origin
must admit to finding this mildly frustrating as i have tried with all sorts of apps ? its the same for all ???????
