Hi @Kalpana_N_A,

Make sure that you are not behind any firewall or network proxy. Also, disconnect from any vpn.

Then try to run the command:

vagrant plugin install vagrant-vbguest

If you still get the same error, please share the details of your Operating System.

Please feel free to reach out if you have any questions.

Kind Regards,
