Fetched 288 kB in 0s (2,349 kB/s) But I have other things to do than spend my time trying to argue with people that we should be allowed to get Linux machines on our corporate network. If you dont want to switch between Windows and WSL when running Windows or Linux containers, you can just expose the Docker Daemon in WSL2 and create a context for it. With this newly-configured DNS resolver (in this case, pointing directly to Cloudflare's DNS server) you can try upgrading packages again. They can still re-publish the post if they are not suspended. But in the end, turned out it was required. Hey, great stuff!
