docker login error saving credentials: error storing credential The name org.freedesktop.secrets was not provided by any .service files

Ubuntu 22.04 の WSL2 で報告されている docker logout/login シーケンスから始め、認証情報の保存と ~/.docker/config.json に焦点を当てます。失敗する credential-helper パスと、文書化されている回避策を比較し、docker login が org.freedesktop.secrets エラーなしで認証情報を正常に保存することを確認します。

Description

Cannot login to the container registry :

id12345@ubuntu2204 ~ $ docker login docker.artifactory.mycompany.com
Username: id12345
Password:
error saving credentials: error storing credentials - err: exit status 1, out: `The name org.freedesktop.secrets was not provided by any .service files`

Reproduce

1. logout ( docker logout docker.artifactory.mycompany.com)
2. login ( docker login docker.artifactory.mycompany.com)

Expected behavior

1. authentication succeeds
2. the credentials are stored into ~/.docker/config.json

Additional Info

Workaround consists in adding credentials manually (not plain text but BASE64 encoded) :

echo -n 'id12345:YOUR_PASSWORD' | base64 -w0

and

cat > ~/.docker/config.json <<EOF
{
  "auths": {
    "docker.artifactory.mycompany.com": {
      "auth": "BASE64_VALUE"
    },
    "docker-public.artifactory.mycompany.com": {
      "auth": "BASE64_VALUE"
    }
  }
}
EOF
