General "git-credential-libsecret not found" error

Question

The git repo have no LFS enabled, but I was prepared git to use in another clone, so use the git config --global credential.helper that seems the cause of the problem.

Seems the same problem here, but I am using updated git (v2.17.0), so it is not a version problem.

Exemple: after simple git pull the message is

/usr/share/doc/git/contrib/credential/libsecret/git-credential-libsecret get: 1: 
/usr/share/doc/git/contrib/credential/libsecret/git-credential-libsecret get: 
 /usr/share/doc/git/contrib/credential/libsecret/git-credential-libsecret: 
 not found

---

NOTES

There are no git-credential-libsecret file,

sudo ls /usr/share/doc/git/contrib/credential/libsecret/git-credential-libsecret
ls: cannot access '/usr/share/doc/git/contrib/credential/libsecret/git-credential-libsecret': No such file or directory

Answer 1

First, make sure to understand where that setting is coming from

git config --show-origin -l

Then you can unset it.
For instance:

git config --global --unset credential.helper

Once the situation is cleaned, you can install back libsecret, as described in "How to bake credential into docker image for git?".
