No, I get a permission error

Maybe you want to make that a less mysterious report by sharing the actual error message?

[ghost]

sorry that is from the issue template.

when cloning a gitea repo, VS code prompt for user name and password like in a HTTP basic auth, instead of using git-credential-manager.

when cloing a github repo, VS code started a pop up window for the oauth as desired.

@dscho could you give me some hint about how to get a debug level log for git-credential-manager when running git clone http://....?

[dscho]

how to get a debug level log for git-credential-manager

The common way is to set the environment variable GCM_TRACE either to 1 (in which case the debug log goes to the standard error output) or to a full path (in which case the log is written to the specified file).

[ghost]

sudo dpkg -i <path-to-package> git-credential-manager configure
and then in a new bash
export GCM_TRACE=1
gives me

the exact repo link works on the same GCM version on windows, though

This is expected. You can't use OAuth on a remote machine because Gitea OAuth requires a desktop web browser:

git-credential-manager/src/shared/Core/Authentication/OAuthAuthentication.cs

Line 44 in 0d23f96

// Browser requires a desktop session!

At least until Gitea implements OAuth Device Authorization Grant go-gitea/gitea#27309 (comment) (as GitHub does).

This one line is not related to vscode remote, but if your git version is older than 2.41.0, it won't pass the WWW-Authenticate header to the credential helper and therefore won't autodetect Gitea. Either configure endpoints manually or update git executable.
