So i have some problem with online update, package newer than established in system, but yast does not show that updating are accessible. Where problem? :(
Do you mean that there is a newer version of the software available from the developer but YaST is not offering you the newer version?
If so it may be that the upgrade has not been packaged for openSUSE yet or you do not have the right repository added.
Let us know the details of the package you want to upgade then we can give you advice.
