Cant install stuff cuz of authentication window getting stuck

Hey i hope u guys can help me… when i try to install acetoneiso rpm it asks me for authentication … i type in the pass but once i click on authenticate, another window pops up … looks like the same but theres not blankspace to type password in… i can click on authenticate again but nothing happends… once in a while it gives me system errors messages or something…

Same with “software update” … i cant do a thing … whats wrong???

Try installing from a console with

su (to become root first)

then

zypper in acetoneiso

Lets see how that goes.

For system-wide update, see if this works

zypper up
