authentication - Cannot login to Docker account

Question

OS: Ubuntu 18.04 Server
Docker 18.3 CE

I am logged onto the server, from my Windows 10 laptop, using a PuTTY SSH session.

I don't have Docker on my local Windows laptop, so all the work is done on the remote server.

I can execute all Docker commands, on the remote server, using the terminal session.

However, when I try to save my image to the Docker hub, when I try to login, using:

docker login

I get the following error message:

error getting credentials - err: exit status 1, out: `GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.secrets was not provided by any .service files`

I did not get any error messages, when I created my image on the remote server.

I also do not see a .docker folder in the related home directory on the remote server. Any ideas?

Edit 2019-04-07:

As this is the currently selected answer, I think people should try @Anish Varghese solution below first as it seems to be the easiest. You only need to install the gnupg2 and pass packages:

sudo apt install gnupg2 pass

If it doesn't work, then you can try my original solution here:

I had the same issue. bak2trak answer worked, but it saved credentials in clear text. Here's the solution if you want to keep them in a password store.

1) Download docker-credential-pass from https://github.com/docker/docker-credential-helpers/releases

2) tar -xvf docker-credential-pass.tar.gz

3) chmod u+x docker-credential-pass

4) mv docker-credential-pass /usr/bin

5) You will need to setup docker-credential-pass (following steps are based of https://github.com/docker/docker-credential-helpers/issues/102#issuecomment-388634452)

5.1) install gpg and pass (apt-get install gpg pass)

5.2) gpg --generate-key, enter your information. You should see something like this:

pub   rsa3072 2018-10-07 [SC] [expires: 2020-10-06]
      1234567890ABCDEF1234567890ABCDEF12345678

Copy the 123... line

5.3) pass init 1234567890ABCDEF1234567890ABCDEF12345678 (paste)

5.4) pass insert docker-credential-helpers/docker-pass-initialized-check and set the next password "pass is initialized" (without quotes).

5.5) pass show docker-credential-helpers/docker-pass-initialized-check. You should see pass is initialized.

5.6) docker-credential-pass list

6) create a ~/.docker/config.json with:

{
"credsStore": "pass"
}

7) docker login should now work

Note: If you get the error "pass store is uninitialized" in future run, run the below command (it will reload the pass store in memory):

pass show docker-credential-helpers/docker-pass-initialized-check

It will ask your password and it will initialize the pass store.
