dotnet tool update form private registry fails

[snailcatcher]

Describe the bug

Try to install a package from a private registry (maybe also non-private, don't know).
Install fails with HTTP 401.

dotnet tool update -g {APP_NAME} --add-source https://pkgs.dev.azure.com/{ORG}/{PROJECT}/_packaging/{FEED}/nuget/v3/index.json --interactive --ignore-failed-sources -v d

fails with:

Error happens when using dotnet cli

[tiagojsrios]

I first saw this issue when my pipeline started failing when running dotnet pack. I realized that my agents started using the .NET 8 SDK to compile my solution (Microsoft rolled out the update). I solved the problem by adding the UseDotNet@2 task to my pipeline (to enforce the correct SDK), having in mind that this could be a potential issue once my team focus in upgrading our solutions to .NET 8.

This week we decided to start the migration and the issue was indeed there. This soon became a blocker for us and therefore we decided to revert the migration. After some investigation, I found the following issue on Stack Overflow: https://stackoverflow.com/questions/77521838/devops-pipeline-suddenly-failing-to-access-artifacts-nuget-feed-unauthorised - which a Microsoft employee (?) was able to reproduce the issue.

An update about this issue.

After spending the weekend without writing any code (neither opening the Visual Studio), I'm currently facing this issue on my local machine.

I don't know if it's related with the way credentials are being refreshed, but I think this is good input. I've also found a post on Stack Overflow from another user potentially facing the same issue.

I feel like a breaking change was introduced with .NET 8. I couldn't find anything on the Breaking Changes in .NET 8 post, so I believe this was introduced unintentionally.

Edit: The only way I managed to be able to pack my nuget was by building the project through Visual Studio with the configuration set to Release (as dotnet pack runs with Release configuration by default since .NET 8).

[foomaniac]

After a nightmare couple of days dealing with this exact issue, I feel like this is going to hit a lot of people real quick, unless we're missing something?

We experienced this issue after .net 8 SDK was downloaded onto our two Hosted Agents. Took me a while to figure out what was going on. We had a new API that was being built in .net 8, and a new pipeline had been setup for it targeting .net 8 SDK. This is what prompted our two hosted agents to download the 8.0.100 SDK.

What happened afterwards was that nearly all our existing .net 6 API build pipelines started failing at the build step.

Each pipeline has a restore step, that is configured to use our Azure Artifacts nuget feed. This step continued to work, however the build started failing due to the same issues above.

Just to note the MS Build version was now the same as the above posters logs:

MSBuild version 17.8.3+195e7f5a3 for .NET

I went down the rabbit hole for an afternoon, first assuming permissions had changed, then assuming I needed to append the --no-restore argument, but to get the build to run I needed to add this to the build, test and publish steps. We have 30+ pipelines.

In the end we've rolled back the new API to .Net 6 and I've manually reset our two hosted agents so neither have the .net 8 SDK available. All pipelines are back to running correctly now.

The kicker is, one of the pipelines has the step to select .net 6 SDK explicitly as below, but the agent still used the .net 8 SDK. Is that a bug too?

[JL03-Yue]

I wonder if it is related to the problem of ignore-failed-source flag

[snailcatcher]

@JL03-Yue if you mean that the flag itself cause the issue, than this is not the case. I tested it out for you:

If I ran the command without ignore-failed-source

dotnet tool update -g {APP_NAME} --add-source https://pkgs.dev.azure.com/{ORG}/{PROJECT}/_packaging/{FEED}/nuget/v3/index.json --interactive -v d

I get the same results:

[lzaromskis]

At least for dotnet tool restore as a workaround you can:

• Change the SDK version in global.json to .NET 7
• Run dotnet tool restore -v n --interactive --no-cache and authenticate when the option is provided
• Change the SDK version back to .NET 8 in global.json
• Run dotnet tool restore which should now complete successfully

Don't know if it would work for dotnet tool update.

[foomaniac]

This is preventing us from committing to utilising .net 8 at the moment due to the impact on all our build pipelines.

Has there been no response at all from Microsoft? Feel like this is pretty big.

[JL03-Yue]

Thank you for the report. This is indeed very important and will look into it.

[snailcatcher]

I talked with some of my colleagues about this. And I noticed something which may be helpful for looking into this problem.

I noticed this "bug" when using a own custom cli tool on my MacOS machine and our Ubuntu Agents in our pipelines (and when dealing with NuGet packages on my Mac).
My colleagues which use Windows machines seem not to have seen this behavior.
So maybe it is an issue either with the dotnet runtime for this specific OSs or it has something to do with the architecture of the underling machine. (My Mac and the Linux machines are mostly arm64, the Windows machines are x64)

Maybe this will help and thank you for the investigations.

[Simon-Gregory-LG]

We get this on Windows Hosted Agents (windows-2022 & windows-latest):

microsoft/azure-pipelines-agent#4556

I've also had it on my local Windows 11 development box in certain circumstances. One thing I've noticed it that it seems to happen frequently if you do the NuGet restore in the dotnet build (i.e. don't specify --no-restore and include a separate dotnet restore step). I haven't looked into it, but I've also seen the same thing in BenchmarkDotNet runs (in .NET 8.0)

[wilkovanderveen]

We are also experiencing this issue and we were able to 'resolve' this using a PAT from in our nuget config, but we need to change all our pipelines accordingly because we dont want to expose the PAT in our nuget.configs

[Vikitorony]

I am experiencing this 401 (Unauthorized) error on Azure DevOps Server 2020 (on-prem), after updating Visual Studio Build Tools 2022 from v17.7.x to v17.8.3.
We use self-hosted agents on Windows Server 2019 and Windows Server 2022. Some agents are running as Network Service (built-in Windows user), and some agents as an Active Directory user.

Previously all commands (dotnet build/pack/publish/test) were running fine on Network Service agents but after updating to Visual Studio Build Tools 2022 v17.8.3 (which includes .NET 8 SDK), all fails with 401 (Unauthorized).

Workaround nr. 1:
As mentioned above, you should run build/publish/test with --no-restore argument. In this case you have to add a dotnet restore task before build/publish/test.

Workaround nr. 2:
If you are running your pipelines on a self-hosted agent, and that agent is not running as an AD user, you should add a new agent to the pool with AD user, or change the associated user to an AD user in service settings.
