Couldn't find any package by glob 'dotnet-sdk-3.1'

[wshaddix]

After following the docs for ubuntu 20.02 I get the error

Couldn't find any package by glob 'dotnet-sdk-3.1'

I then followed the docs for troubleshooting this issue, mainly running

sudo dpkg --purge packages-microsoft-prod && sudo dpkg -i packages-microsoft-prod.deb

and then tried to install dotnet-sdk-3.1 but I still get the exact same error

The 20.04/focal repository doesn't contain the packages yet. Looks like it still only has placeholder packages: https://packages.microsoft.com/ubuntu/20.04/prod/pool/main/

I have the same issue though i was able to use the package from the snap store.

I was also able to get it from the snap store, thanks for the heads up @thebf !

Never mind, the dotnet cli tools are not quite available so certain aspects of working with aspnet core is not smooth with the snap store approach

This is right--there are are some workarounds in the dotnet/core issue about this: dotnet/core#4360. I've asked there if the 20.04 page should be taken down (since we don't have packages on the repo yet) or we could potentially publish workaround instructions.

I was able to get dotnet working on Ubuntu 20.04 using the .NET core script and then adding the path variables to both ~/.profile and ~/.bash
https://dotnet.microsoft.com/download/dotnet-core/scripts

[Thraka]

@dagood I thought it was released and ready? Was I wrong? I must have crossed some wires somewhere.

真的能找到 非常感谢

Removed the article for now. Once it's actually ready, I'll republish the article. Ack!

[dagood]

Thanks! For anyone who hits this thread later--workarounds and the status of getting .NET Core packages released for 20.04 are at dotnet/core#4360.

I typed these commands and it worked:

sudo apt-get install -y gpg
wget -O - https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor -o microsoft.asc.gpg
sudo mv microsoft.asc.gpg /etc/apt/trusted.gpg.d/
wget https://packages.microsoft.com/config/ubuntu/22.04/prod.list
sudo mv prod.list /etc/apt/sources.list.d/microsoft-prod.list
sudo chown root:root /etc/apt/trusted.gpg.d/microsoft.asc.gpg
sudo chown root:root /etc/apt/sources.list.d/microsoft-prod.list
sudo apt-get update &&
sudo apt-get install -y dotnet-sdk-3.1

But now I formatted my PC and I'm trying to install again but the error appears as if I didn't type the above commands.
