Comment 2 for bug 1905085

I need the authentication screen in order to use the synaptic package manager and the ubuntu software which I can not access by now and I can not install any new applications because they ask me for my password; I can not send you any screenshots of the authentication pop up because it is modal when it appears and blocks the whole screen,of course,I also need the sudo very badly to do many things I am currently doing.Awaiting for your news. Thanks.
