I just installed Ubuntu on a virtual machine hosted by windows 10



It's been few hours that I am trying to find solution this problem:

I found this simular question
sudo apt update always giving Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?) but there are only two answers:



  • One:It suggests that it's a network problem specific to my ISP. (How can I be sure? Then what can I do solve it)

  • Two: It's a proxy problem, so I make the following configuration

What should I replace <proxy> ?
