# `install.fetch_failed`

Package's git repository or tag couldn't be read.

Area 14, [Tooling](../topics/tooling.md); not declinable; the next step is usually the human's.

A git repository that can't be read, or holds no release to install:

```text
$ jadpo package add github.com/acme/postcodes@v9.0.0
error: `github.com/acme/postcodes` has no tag `v9.0.0`
  reason: Its release tags are `v2.0.0` and `v2.1.0`.
  next: Give one of its release tags, or tag the release in the package's repository after `jadpo package check` passes (human)
  rule: install.fetch_failed
