I am running ubuntu 20.04.1 VMware. When its network adapter is bridged, I can not do sudo apt update, meanwhile I can ping 8.8.8.8 or even ping google.com . If I change its network adapter to NAT mode, I can do sudo apt update.

What are the differences? and how can I have sudo apt update in the bridged mode too?

Any comments would be appreciated!

here is the output of the sudo apt update:

My host pc has two network interfaces, both of them are connected (wired) to an access point which are connected to internet!

  • Welcome to Ask Ubuntu. How is your host PC connected to Internet: Wired or wireless, Private or public network, home or school/company? Do you have a proxy setup? – user.dz May 31 '21 at 14:13

  • So they are connected to the same subnet, that's probably the issue. Unplug one interface, and use only one (don't forget to use bridged connection through active one) – user.dz Jun 01 '21 at 08:19

  • Just change the server from US to UK or UK to US or from the server for the United States to the main server or vice versa. Then reload the software cache. Sometimes you find the servers unavailable or being down or some network issues. – N.Ahmed Feb 06 '23 at 17:49
