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’.
I narrowed it down and updated all package except the ‘Welcome’ package which still produces the same message when attempting to update. I have also tried fixing broken packages through the Software Boutique. Is the problem related to the Software Updater or the ‘Welcome’ package? @wizd3m
It seems that one of the packages needs a new key. Did you install Virtualbox? Then it is correct you get this error when upgrading (either through Software Updater or manually).
This has already been reported and a fix is on the way.
I didn’t install Virtualbox. Strangely it updates correctly on my main machine, a Lenovo Thinkpad T460 (now with Version 16.10.0-xenial 1.1) but I still get the error message with no possibility to update the Welcome package on my older Lenovo Thinkpad X61 (with Version 16.04.9). So it seems not related to Virtualbox in my case.
