Nothing to do.
If i understand the code correctly i seem that fuse is not installed or? Correct?
In my opinion aptitude does not sound very openSUSE like. Maybe others know better what it is and does.
But when it is somethinmg to install packages (for what we normaly usr zypper or YaST > Software > Software management), then it seems that the packages mentioned can not be found in any repository you have configured.
Normaly fuse is installd by default on openSUSE. You can of course check that with YaST > Software > Software management en typing fuse in the Search field.
