error: use of deleted function while implementing listview

[drd1988on]

Hi
I am implementing a listview inherited from QAbstractListModel.
Am getting error like "use of deleted function ‘VEN_UI::Model::PackageModel& VEN_UI::Model::PackageModel::operator=(const VEN_UI::Model::PackageModel&)"
Here is my code
#include "inc/packagemodel.h"
using namespace VEN_UI::Model;

                                      PackageDetails::PackageDetails(const QString &name, const QString &version)
                                          : m_pkgName(name), m_pkgVersion(version)
                                      {
                                      }
                                      
                                      QString PackageDetails::pkgName() const
                                      {
                                          return m_pkgName;
                                      }
                                      
                                      QString PackageDetails::pkgVersion() const
                                      {
                                          return m_pkgVersion;
                                      }

                                      void PackageModel::addPackage(PackageDetails* pkgDetails)

@drd1988on In which line do you get this error?
You seem to assign PackageModel somewhere and assignment operator is disabled (deleted).
