A solution for the failure to recognize and accept proper root passwords in R8 MATE 64bit continues to elude me. Not only does this error show up when attempting to use Gdebi, but it shows up in anything else I run that needs root authorization.
The latest was with Virtualbox. Downloaded the latest VB .deb file and successfully installed it by running gdebi-gtk in Terminal. Once Virtualbox was installed, when I sought to add the latest VB Extensions to it Virtualbox itself asked for root authorization to do so. When I *correctly* entered my root password I was once again informed that my password was "incorrect".. Not good!!
Don't know for sure what it will take to correct this wide spread issue, but for the moment it's on the brink of being a deal breaker with WattOS R8 MATE 64bit -- at least with newbies, till it's finally and completely fixed.. Any working solution would be MORE than welcome!!!..
