I have downloaded and installed Synaptic. When I attempt to run this error message appears:
There are two or more versions of the package 'j2sdk' installed in your system, which is a situation APT can't handle cleanly at the moment.
Please do one of the following:
1) Keep at most one version of the package in the system; or
2) If you do want to keep multiple versions of that package, lookup RPM::Allow-Duplicated in the documentation.
Error occured while processing j2sdk (UsePackage3)
Problem with MergeList /var/lib/rpm/Packages
