WSL2 update and apt-get failure, though ping works fine

I am trying to get Ubuntu running using WSL2 on my office laptop.

Problem : When I try to run apt-get update or any install command, eg : apt-get install gcc, it always ends up with 101 : Network is unreachable.

Solutions I have tried so far :

  1. Firewall

My initial guess was that my office firewall may be blocking the connection, but on wuick ping check i see that it works fine. Also I have browsed the URL's in chrome and it works without any issues.

$ ping 91.189.91.39
PING 91.189.91.39 (91.189.91.39) 56(84) bytes of data.

  1. resolver configuration file issue.

I have tried changing the default nameserver to 8.8.8.8 and other DNS providers as well but didn't resolve the issue. Also since ping works, DNS resolver shouldn't be a problem.

Now there are few more solution which I am able to find, like forcing apt to use IPv4, deleting hypervisor switching adapter and other such solutions but their problem doesn't seem to corelate with what I am facing and I don't want to keep shooting arrows in dark.

Any help or direction pointing will be very much appreciated. Thank you

Can you try it from home (or anywhere else) while not connected to the company network? Also, is there any VPN involved? Thanks!

Sorry, I wanted to comment the question with these information but my reputation is too low to do it. I suggest to give a try to [wsl-vpn](https://github.com/AmmarRahman/wsl-vpn) which is a networking solution I've seen solving issues in many similar use cases (ping/ICMP working, HTTP/HTTPS/DNS/etc. not working) It leverages [moby-vpnkit](https://github.com/moby/vpnkit) and [npiperelay](https://github.com/jstarks/npiperelay) and it works by creating a "data-tunnel" between WSL2 and the Windows host, specifically a pipe. This means a Windows service is always listening. You get the best of almo

Above method actually requires to install docker, which I will not be able to due to company policies. Thanks for the solution though.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
