How to solve errors on git remote repository access
Sometime, we encounter error to pull or push repository from github, gitlab or company’s remote git space. I like to keep note about how I do resolve it for my future work.
git status

$ git status
On branch master
Your branch is up to date with 'origin/master'.
nothing to commit, working tree clean
|
- If
git status says there are anything unstaged or not committed in local repository, do git add <file path> and git commit -m <commit message>.

$ ssh -T git@gitlab.com
Welcome to GitLab, @hoge!
|
- If
ssh -T returns Permission denied (publickey).,
- check
~/.ssh/config and whether the right ssh-key is configured for the remote URL domain. For example,

$ vim ~/.ssh/config
Host gitlab
Hostname gitlab.com
UseKeychain yes
AddKeysToAgent yes
IdentityFile ~/.ssh/id_rsa4
|
-
In the above case, If the public key of id_rsa4 (the file name should be id_rsa4.pub) is not registerred to github/gitlab,
- Register it at github/gitlab > settings > SSH key, register that public key.
-
If local ssh file configuration is right and remote public key was registered, but you cannot access to remote, you should check git remote -v below.
Check .git/config (Add 2021.05.11)
Check .git/config and check remote origin url.
If url has https address, this repository directs to remote orgin url over https.

[remote "origin"]
url = https://github.com/tatoflam/canvas-lms.git
|
Sometime, you can fix some error prevention by specifying remote origin url over ssh.

[remote "origin"]
url = git@github.com:tatoflam/canvas-lms.git

git remote -v

$ git remote -v
origin git@github.com:mraardvark/pyupdi.git (fetch)
origin git@github.com:mraardvark/pyupdi.git (push)
|
- If above command returns error or different URL, You might need to add remote repository,
1
|
$ git remote add origin git@github.com:mraardvark/pyupdi.git
|
- Or change remote repository URL.
1
|
$ git remote set-url origin git@github.com:mraardvark/pyupdi.git
|
- If
git remote -v returns the url address beginning from “https” like origin https://gitlab.fabcloud.org/academany/..., your remote url setting is to set by HTTPS. HTTPS sometime requires local client credential and it may brings error.
Add ssh key to ssh-key agent.
Sometime, you need to add ssh key locally to ssh-agent by ssh-add.
