This issue comes up several times.

I got two modules that tagged as same `version`.

| Module | Version |
| --- | --- |
| `hb` | `v0.1.2` |
| `hb/modules/meta/docs` | `v0.1.2` |

> The `hb@v0.1.2` is released earlier than `hb/modules/meta/docs@v0.1.2`, which doesn’t include the `docs` submodule.

I got the following error when I try to upgrade to `hb/modules/meta/docs@v0.1.2`.

```sh
➜ hugo mod get -u github.com/razonyang/hb/modules/meta/docs@v0.1.2
go: module github.com/razonyang/hb@v0.1.2 found, but does not contain package github.com/razonyang/hb/modules/meta/docs
Error: failed to get ["-d" "-u" "github.com/razonyang/hb/modules/meta/docs@v0.1.2"]:

but does not contain package github.com/razonyang/hb/modules/meta/docs
 *errors.errorString

➜ hugo mod get github.com/razonyang/hb/modules/meta/docs@v0.1.2 
go: module github.com/razonyang/hb@v0.1.2 found, but does not contain package github.com/razonyang/hb/modules/meta/docs
Error: failed to get ["-d" "github.com/razonyang/hb/modules/meta/docs@v0.1.2"]:

 *errors.errorString

```

But it’s strange that everything works fine after running `go get`.

```sh
➜ go get -u github.com/razonyang/hb/modules/meta/docs@v0.1.2
go: downloading github.com/razonyang/hb v0.1.2
go: downloading github.com/razonyang/hb/modules/meta/docs v0.1.2
go: upgraded github.com/razonyang/hb/modules/meta/docs v0.1.1 => v0.1.2

➜ hugo mod get -u github.com/razonyang/hb/modules/meta/docs@v0.1.2

➜ hugo mod tidy

➜ git diff | grep docs
- github.com/razonyang/hb/modules/meta/docs v0.1.1 // indirect
+ github.com/razonyang/hb/modules/meta/docs v0.1.2 // indirect

```
