I have just installed Ubuntu 24.04. When i try to run "sudo apt update" it throws the below error. I have tried:

  • changed "Download from" server from main to other server in software & updates. But it still shows the same error.
  • run sudo apt upgrade before update
  • checked proxy in network setting and it is off
  • I am using wifi connection so i changed dns from wifi connection setting to 8.8.8.8 and 8.8.4.4 but it didn't help so i changed back

Error:

    Is this machine on a restricted network that is filtering traffic (ie. letting some thru & blocking traffic that is unknown) such as a school, corporation etc. Your details read like a network issues to me (ie. DNS functioned, but then traffic was blocked..) Alternatively you're using an incorrect repositories for your unstated architecture; but that would require you to have incorrectly modified your sources/mirror...

    This looks like a network problem. Those mirrors work.

Selecting Best Serever from software & update solved the issue. The download server was changed to "mirrors.cloud.tencent.com/ubuntu".

Software & update screenshot

But the below nobel-security release issue was still there.

Ign:2 http://security.ubuntu.com/ubuntu noble-security InRelease                    
Err:3 http://security.ubuntu.com/ubuntu noble-security Release

So i commented code for security URIs and added "nobel-security" to the top Suites. Here is updated code of ubuntu.sources

Types: deb
URIs: https://mirrors.cloud.tencent.com/ubuntu/
Suites: noble noble-updates noble-backports noble-security
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg
