This happen on almost all official WSL distros (suse, debian, ubuntu) . I have not tried kali yet but i think the result will be the same.

This is the report on ubuntu:

• Windows build number: 10.0.18932.1000

• What you're doing and what's happening:

  • try to run sudo apt-get update

• What's wrong / what should be happening instead:

  • Error message:

  • This seem like a dns issue, this is the content of my 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 172.22.64.1

  • Run ipconfig from cmd and overwrite resolv.conf with the dns I get from ipconfig. Run apt-get update again. Host name can be resolved now, but get another error:

  • Try disable firewall, still the same error. I only use window defender, no other antivirus.

  • I convert my distro back to WSL 1 and every network command work fine. The content of resolv.conf in WSL 1 is surprisingly the same as when I overwrite the one in WSL 2

  • Expected: commands that require internet work as WSL 1

• Strace of the failing command, if applicable: can't, strace has not been installed yet beacause no internet. (I run strace on debian and got the command not found error, so I think ubuntu doesn't have them pre installed too). The log is quite long (3k+ lines) so I put them in a file:
  apt-strace.log
