I don't know why fetch causes the error.

[Self-solved] Thank you.

"From ""B"" to ""git remote-v""

origin/Users/MBP/shared_repo.git(fetch)
origin/Users/MBP/shared_repo.git(push)

So, from "Mr. A," "git fetch/Users/MBP/shared_repo.git" passed.

Based on the question and comment text and the linked documentation,
/Users/MBP I think there are three directories below.

• takashis_workspace (first repository created; no remote repository configuration)
• shared_repo.git (bare repository cloned with takashis_workspace)
• yuusukes_workspace (a repository cloned with shared_repo.git)

From this state, you have to configure the remote repository for takashis_workspace.

Let's set up a remote repository so that Takashi can reflect changes to the repository that everyone touches and retrieve changes from it.To add a remote repository, use git remote add<name of remote repository><location of remote repository>.

$git remote add origin path/to/shared_repo.git

I think the place where this command was executed was /Users/MBP/takashis_workspace.In that case, the actual command to execute is

$git remote add origin../shared_repo.git#relative path specification

Or

$git remote add origin/Users/MBP/shared_repo.git#absolute path specification

will be .
The reason why it is not working as expected this time is

$git remote add origin shared_repo.git

This is probably because you have specified a non-existent location.

Correct the repository location pointed to by origin and it will return to its original location.

There are several ways to do this, but I think it's easy to remove the wrong setting in origin and reset the correct value.

Specifically, in the /Users/MBP/takashis_workspace directory:

$git remote origin
$ git remote add origin../shared_repo.git

There is also a way to specify the repository, but in this case origin is misconfigured, so I don't think it will work as described in the following documents.
