No URL was provided to upload the provider You will need to

Error message

No URL was provided to upload the provider
You will need to run the `vagrant cloud provider upload` command to provide a box

What it means

Warning from `vagrant cloud provider update` (plugins/commands/cloud/provider/update.rb) when the invocation carries no --url. Exactly like provider create: the update still proceeds (checksum, architecture, default_architecture fields are applied; p.url = url if !url.nil? leaves the URL untouched), but the notice reminds you the provider's hosted box file can only be supplied via `vagrant cloud provider upload`.

Solutions

1. After a metadata-only update, push the artifact with `vagrant cloud provider upload org/box 1.0.3 virtualbox --architecture amd64 --file ./new.box`.
2. If the artifact is self-hosted, include --url https://... in the update command to set/replace the download URL directly.
3. Use `vagrant cloud publish` with the box file path for a create-or-update flow that guarantees an asset.
4. Confirm the final state with `vagrant cloud box show org/box` (URL present / file size updated).

Example fix

# before
vagrant cloud provider update myorg/app 1.0.3 virtualbox amd64 --checksum abc123
# -> No URL was provided ...

# after (artifact hosted remotely)
vagrant cloud provider update myorg/app 1.0.3 virtualbox amd64 \
  --checksum abc123 --url https://cdn.example.com/app-1.0.3.box

if [ -z "$BOX_URL" ] && [ ! -f "$BOX_FILE" ]; then
  echo "update carries no asset: pass --url or run cloud provider upload after" >&2
fi

When it happens

Trigger: Running `vagrant cloud provider update org/box 1.0.3 virtualbox amd64` without --url while updating metadata such as --checksum/--checksum-type; any metadata-only refresh of an existing provider entry.

Common situations: Rotating checksums after re-signing artifacts; updating default_architecture flags; operators who believe update also uploads the file — it does not, the warning marks the gap.
