I have tried with below setting but not working
Window-> Preferences-> General->Network connection->Active provider- Manual
Error details: Cannot open eclipse market place Cannot install eclipse market place location: Connection failed
This most often caused by a problem with your internet connection.
I'm not sure why it happens to you (I guess you probably have a spotty net connection or some firewall in place).
Other things you can try:
install without using the marketplace client. See: http://www.pydev.org/download.html for details (i.e.: you can use http://www.pydev.org/updates as the update site).
download a .zip from sourceforge (https://sourceforge.net/projects/pydev/files/pydev/) and then extract it yourself in the Eclipse
dropins
folder (and restart Eclipse).
