Operating System: Ubuntu 20.04 Getting this issue when using dotnet commands.

/snap/dotnet-sdk/228/sdk/8.0.100/NuGet.targets(156,5): error : Unable to load the service index for source https://api.nuget.org/v3/index.json.

I think there are issues with snap installs. I'd try a different installation method: https://learn.microsoft.com/en-us/dotnet/core/install/linux-ubuntu

[Anudeep-Akella]

Thank you for the advice.

Encountering the same error even after deleting and installing the dotnet by following the above link. user@elementary:~$ dotnet new console

@leecow @NikolaMilosavljevic who can help with install issues like this?

[Anudeep-Akella]

Thank you for the suggestion.Do you think the problem is with not setting up the env(Environmental Variable). Also i am new to github how can i ask my problem to the persons directly you mentioned.

I successfully ran things on a new 20.04 machine, so we know it works! :-).

@Anudeep-Akella - a couple of things to help me understand the state of your machine.

• confirm the Snap installed .NET is gone by running snap list in a terminal. Make sure 'dotnet' anything is not listed.
• run dotnet --info and share the entire output.
• try dotnet new console in a different directory. (want to make sure you're not re-using what was started with the Snap installed .NET)

[Anudeep-Akella]

Thank you for the advice. I am seeing that the dotnet is listed in the snap list.

This is the output i got after running dotnet --info. user@elementary:~/My$ dotnet --info .NET SDK: Version: 8.0.100 Commit: 57efcf1350 Workload version: 8.0.100-manifests.6c33ef20

[Anudeep-Akella]

Hlo, Do you mind telling me how to setup all the Enviroment and global variables for dotnet.

[rzikm]

The output from dotnet --info suggests it is still using the snap installation. Can you try uninstalling the snap version of dotnet first?

[Anudeep-Akella]

Thank you for the Advice. I uninstalled dotent from snap and installed using sudo apt install dotnet-sdk-8.0.

I tried to reproduce the issue on the elementary/docker:stable docker image and it does not happen there.

The error message suggests we are trying to send malformed HTTP headers during nuget restore. @nkolev92 Can you please advise for the next steps and transfer the issue if applicalbe?

[mairaw]

@nkolev92 can you please advise here?

[nkolev92]

I'm not sure how that would happen. Don't remember seeing this before. What I'd try doing is increasing the verbosity, and/or using a network inspection tool to figure out what characters are being reported as non ascii.
