When I try to update software in UM 16.04 through the Software Boutique, I get the following message: “Requires installation of untrusted packages”. Clicking ‘ok’ does not lead to any actual download. What am I doing wrong?
When I click on System > Administration, I can see three entries relating to Software. This is very confusing: Software Boutique, Software Updates, Software & Updates. What is the difference between these and is there a need to keep them separate? Why not unify all of them under one window? When I click on ‘Software Updater’ no updates get installed. Each time a new window pops up: ‘Requires installation of untrusted packages’.
