I cannot update Ubuntu 20.04 since 2/11/2022. I am connected to the internet wirelessly, on a private network at my home. There is no proxy set up. My main OS is Windows 11.

I tried to update Ubuntu in VirtualBox and used WSL2 with the same result.

Pinging localhost works the same for the IP that is inside of /etc/resolv.conf

sudo apt-get update:

Err:1 http://security.ubuntu.com/ubuntu focal-security InRelease

I can ping cat resolv.conf

# This file was automatically generated by WSL. To stop automatic generation of this file, add the following entry to /etc/wsl.conf:
# [network]
# generateResolvConf = false
nameserver 172.23.224.1

ping localhost

  • I don't understand how you are trying to update Ubuntu in both VirtualBox and WSL. How and where is Ubuntu installed? It can't be both. – Nmath Feb 12 '22 at 07:26
  • Do you have some firewall or antivirus installed? – Kulfy Feb 12 '22 at 10:56
