Solutions

1. Verify the exact NuGet package name on abp.io/NuGet and retry.
2. Check spelling and casing of the requested package name.
3. Confirm network connectivity so the full package list is returned; retry on transient failures.

var packages = await nugetProvider.GetPackageListInternalAsync();
if (!packages.Any(p => string.Equals(p.Name, name, StringComparison.OrdinalIgnoreCase)))
    throw new ArgumentException($"NuGet package '{name}' not found.");

static async Task<bool> NugetPackageExistsAsync(NugetPackageInfoProvider provider, string name)
{
    var list = await provider.GetPackageListAsync();
    return list.Any(p => string.Equals(p.Name, name, StringComparison.OrdinalIgnoreCase));
}

try { await nugetProvider.GetAsync(name); }
catch (Exception ex) when (ex.Message.Contains("Package is not found"))
{
    logger.LogError("NuGet package '{Name}' not found or not downloadable.", name);
    throw;
}

When it happens

Trigger: Requesting NuGet package info via the CLI with a package name not present in the remote NuGet package list.

Common situations: Typo in the NuGet package name; package renamed/deprecated; commercial package requested without entitlement; partial list due to network issues.
