publish a nuget package from a copy - azure-devops

Question

It seems my team mates have turned off their nuget server and gone on holidays.
I need a temporary work around so that my Azure Dev Ops build does not fail when restoring the nuget packages.
I have a local copy of the package at
C:\Users\kirst.nuget\packages\mypackagetemp
Which I want to publish to a temporary feed.
I read the instructions on publishing a package from the command line but am confused about step 6
Surely I dont need to set up the Project and restore packages as I already have the .nupkg
I tried the command
c:\nuget\nuget.exe push -Source "TempFeed" -ApiKey az mypackagetemp.nupkg
but got an error
unable to load the service index for source
https://pkgs.dev.azure.com/mycompany/myproject/_packageing/TempFeed/nuget/v3/index.json
When I repeat the command I get a request for credentials
When I put in the credentials I connect to Azure Dev Ops with they do not work.
[Update]
I was prompted for credentials.. reading up on it... so confusing.
[Update]
I upgraded nuget.exe from 5.1.0.6013 to the latest version 5.4.0.6315 This time I got a UI to log in and the message
Your package was pushed
However when the devops pipeline build runs I het a message
unable to load the service index for source
https://pkgs.dev.azure.com/mycompany/myproject/_packageing/TempFeed/nuget/v3/index.json
I guess I need to create an index.json file somehow.
My project is using a mynuget.config that has the following in the packagesources
<add key="TempPackage" value="https://pkgs.dev.azure.com/mycompany/_packaging/myfeed/nuget" />
[Update]
I changed mynuget.config to have
<add key="TempPackage" value="https://pkgs.dev.azure.com/mycompany/_packaging/myfeed/nuget/v3/index.json" />
Now the dev ops build shows the message
Failed to retrieve information about 'Serilog.Enrichers.Thread'
from remote source
'https://pkgs.dev.azure.com/mycompany/_packaging/myfeed/nuget/FindPackagesById()?id="Serilog.Enrichers.Thread'',
response status code does not indicate success: 404 (Not Found).)
My solution does use Serilog. I don't think the 3rd party package uses it.
[Update]
The next time I built I got a different error looking for WindowsAzure.Storage
I seem to get a different file causing the error each time I build the pipeline.
My project artifacts does have 2 feeds. The needed files are in the unselected feed.
[Update]
I tried editing mynuget.config to use index.json however I get a build error
The nuget command failed with exit code(1) and error(Unable to load
the service index for source
https://pkgs.dev.azure.com/mycompany/_packaging/myfeed/nuget/v3/index.json.
Response status code does not indicate success: 404 (Not Found - The
feed with ID 'MyFeed' doesn't exist
[Update]
Because the new feed was project based I edited mynuget.config to have
<add key="TempPackage" value="https://pkgs.dev.azure.com/mycompany/myproject/_packaging/myfeed/nuget/v3/index.json" />
Now it works!

In Azure Devops web portal, for your current project, go Artifacts tab and make sure your packages like mypackagetemp.nupkg are available there.
For me, I have custom LibraryCore.nupkg pushed there. Now let's click the Connect to feed settings, choose nuget.exe and you can see:
Copy exactly same content to your own mynuget.config file. Then your build pipeline can access your published mypackagetemp.nupkg.
Failed to retrieve information about 'Serilog.Enrichers.Thread' from
remote source
'https://pkgs.dev.azure.com/mycompany/_packaging/myfeed/nuget/FindPackagesById()?id="Serilog.Enrichers.Thread'',
response status code does not indicate success: 404 (Not Found).)
The next time I built I got a different error looking for
WindowsAzure.Storage
These packages(Serilog.Enrichers.Thread,WindowsAzure.Storage and ...) are all available in nuget.org, so you should also make sure you've add nuget.org as package source in your config file:
In addition:
According to your description, you only need to use your custom devops feed and other packages from nuget.org, apart from using your mynuget.config, you could configure your nuget restore task like this:
Choose devops feed directly(second red line) by Feeds I select here instead of Feeds in my Nuget.config. And check the Use packages from nuget.org checkbox. Then you can access the packages in custom feed and nuget.org during build.
