I made a Ubuntu Server 20.04 VM in Hyper-V and whenever I try to run sudo apt-get update I get the following return:

W: Some index files failed to download. They have been ignored, or old ones used instead.

I'm able to ping and I can also download docker images and use sudo apt-get update inside a docker container. So I assume I do have some sort of network connection?
Does anyone know what I did wrong or how I can fix this?
Thanks!

Edit:
I'm able to ping to 8.8.8.8 and be.archive.ubuntu.com as well!

This is likely a cause of Your firewall conflicting with your network proxy.They way firewall is configured (factory settings in mind) is that it places stricter protocol on network traffic.When combined with a proxy, that takes your Ipv6 and sends it to a server bank, then to the target domain.

When a proxy(s) become overloaded, it causes a massive slowdown in traffic. 8.8.8.8 is Google's standard dock address, and is slow( at least when I use it).The proxy you're using is likely the cause for DNS timeout. I would advise doing the following:

1.Check to see if your firewall is blocking a port

        sudo telnet google.com 80

2.If you recieve an error, simply go to the activities page to launch the firewall gui and unblock port 80.I would personally disable the proxy via wifi settings or ethernet

3.If apt-get update is still not working, it may be due to the software repositories.If you are tuned to recieved pre-releases, then you may have to remove those pre-release packages.

 sudo apt-remove [name of repository]

Then,go to Software and Updates on Activities, uncheck Pre-Release.

I am New to answering and interacting on this site, so I sincerely apologize for any editing mistakes.

I hope this helps, best of luck.

  • Hi! Thank you for your reply. I've tried unblocking port 80 because I got an error from the first command. However, after trying these changes I'm now somehow unable to even use SSH. So I don't really know what I did wrong. Thank you so much for replying though! – ncxzthkta Nov 26 '21 at 10:20
  • For SSH errors, verify that the host IP Address is correct for the droplet.Verify that your network supports that SSH block.Some internet providers may block port 22 or custom SSH ports.Also check to see that they are not set to a default policy of DROP, and the port is not added to allow connections. – GravvyBoiiz Nov 27 '21 at 01:14
