Installing ASP.net on Ubuntu 20.04

Question

I'm trying to add ASP.net onto my Ununtu 20.04 server. As per:

https://docs.microsoft.com/en-us/dotnet/core/install/linux-ubuntu

They tell you to:

wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb

Thats all good, apart from it gives a 404!

Resolving packages.microsoft.com (packages.microsoft.com)... 13.81.215.193
Connecting to packages.microsoft.com (packages.microsoft.com)|13.81.215.193|:443... connected.
HTTP request sent, awaiting response... 404 Not Found
2021-06-17 06:04:56 ERROR 404: Not Found.

Is there another way to do this? I've searched around, but can't find anything about the key being a 404. Thanks!

FWIW this is really weird! If you check out M$'s website:

https://packages.microsoft.com/config/ubuntu/20.04/

You can see the file - but when you click on it, sure enough its a 404:

https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb

UPDATE: I found this page:

https://docs.microsoft.com/en-us/windows-server/administration/linux-package-repository-for-microsoft-software

That got some of it working - but I now get:

root@south:/home/ebay# apt-get install dotnet-sdk-3.1

UPDATE: M$ have fixed their repo, and it lets me install now!

@GeraldSchneider any ideas on who to contact out of their millions of staff? :) Not sure what their official channel is — Andrew Newby, Jun 17 '21 at 07:21
There is a button "Support" on their website. Personally, I'd probably start with their community forums. — Gerald Schneider, Jun 17 '21 at 07:24
@GeraldSchneider OMG I can't even find where to do that! I tried going through to https://support.serviceshub.microsoft.com/supportforbusiness/create , but once I had written up the whole question, it then tells me: "We were unable to find an eligible support plan associated with your account. Please add a support plan from the options below.". They want me to pay £200 for a one-off report, for their screw up :( — Andrew Newby, Jun 17 '21 at 07:40
ok I posted here: https://docs.microsoft.com/en-us/answers/questions/440043/404-for-packages-microsoft-proddeb-when-trying-to.html — Andrew Newby, Jun 17 '21 at 07:45
@GeraldSchneider FYI, it seems like lots of others have also noticed it: https://github.com/dotnet/docs/issues/24718 . Hopefully they fix it soon :) — Andrew Newby, Jun 17 '21 at 09:40

Microsoft have now sorted this. Was an issue their end (and a lot of pretty miffed developers chasing them down)
