I need help with this error message.

Hello Linus folks!

I have a problem and I get this error. Not every user is affected and some may come in and some may get this message (look attachment).
Are any of you familiar with this problem and I wonder if you could help me.

Try again, if it still doesn#t work then I'm guessing it's your DNS server you're using not resolving the name for some reason. Go into network and sharing center (right click network icon), click on your network connection adaptor (in blue) eg ethernet... click on properties, left click (highlight/select) on "internet protocol version 4, but do NOT untick the box... then click properties. Click the round (radio button) where it says "use the following DNS servers" and then tyoe into the boxes 8.8.8.8 and 8.8.4.4, this will change the DNS servers to googles instead of your ISPs... then click OK at the bottom. Restart your PC, not really necessary, but just to save possible problems. Then try again.
