Installing all packages from {0} is not supported.{1}Only in

Error message

Installing all packages from {0} is not supported.{1}Only internal NuGet repositories are supported.

What it means

SetRemotePackageNamesIfAllSpecified refuses the 'all' keyword when the configured sources include any public NuGet feed (ApplicationParameters.PublicNuGetSources). Bulk-installing everything from public repos is unsupported; only internal repositories are allowed, so it throws ApplicationException.

Solutions

1. Specify explicit package names instead of 'all'
2. Scope the command to an internal source only (choco install all --source=<internal-repo>)
3. Disable public sources for the run before using 'all'
4. Set up and use an internal NuGet repository as the sole source

Example fix

// before
choco install all
// after
choco install all --source=https://internal-feed/nuget

// Reject 'all' before invoking when any public source is enabled.
var publicSources = ApplicationParameters.PublicNuGetSources.Select(s => s.TrimEnd('/'));
if (config.PackageNames == ApplicationParameters.AllPackages && config.Sources.Split(',').Any(s => publicSources.Contains(s.TrimEnd('/')))) {
    throw new InvalidOperationException("'all' is not allowed with public NuGet sources; specify names or use an internal source.");
}

try { choco.Install(config); }
catch (ApplicationException ex) when (ex.Message.Contains("Installing all packages")) {
    logger.Error(ex.Message); // switch to explicit names or an internal source
}

When it happens

Trigger: Running choco install/upgrade/list with PackageNames equal to ApplicationParameters.AllPackages ('all') while config.Sources contains a public NuGet URL (trimmed of trailing '/') from PublicNuGetSources.

Common situations: User passes 'all' while the community/chocolatey public source is still enabled; a script reuses 'all' across a mixed source list including a public feed; CI config mistakenly sets PackageNames=all with default sources.
