  • First login with by entering login name(this is your username) and password
  • Run sudo apt-get update
  • If above step fails run the command which is given in the error. Usually this is something related to dpkg.

So downloading each one is a very difficult task because there are problems like versions don't match, some libraries are outdated, etc.etc. There is a easy method. After installing the plugin Netbeans will automatically add the Jasper Reports library to its library collection. But it is missing one important...
