Unable to log in
Docker Desktop relies on passto store credentials in gpg2-encrypted files.
Before signing in to Docker Hub from the Docker Dashboard or the Docker menu, you must initialize pass. Docker Desktop displays a warning if you've not initialized pass.
Pass
Pass is the standard unix password manager.
With pass, each password lives inside of a gpg encrypted file whose filename is the title of the website or resource that requires the password. These encrypted files can be manipulated using standard command line file management utilities.
pass makes managing these individual password files extremely easy. All passwords live in ~/.password-store, and pass provides some nice commands for adding, editing, generating, and retrieving passwords.
It is a very short and simple shell script. It's capable of temporarily putting passwords on your clipboard and tracking password changes using git.

Solution
Check your OS (optional)
This step is just to ensure you have Fedora 38 Linux installed. You can pick up one command or you can use them all.
/etc/os-release
COPY
COPY
cat /etc/os-release
hostnamectl
COPY
COPY
hostnamectl
Output
When you run hostnamectl without any options, it provides detailed information about the system's hostname, operating system, kernel, and other system-related settings.
lsb_release
lsb_release -a
Output
lsb_release is a command-line utility commonly found in Linux distributions that adhere to the Linux Standard Base (LSB). The LSB is a standardization initiative that aims to increase compatibility between different Linux distributions by defining a common set of libraries and conventions.
uname
uname -a
Output
The uname -a command is used to display detailed system information about the Linux operating system. It provides information about the system's kernel and other system-related details.
Pass is not initialized
pass
Output
Generate a gpg key
gpg --generate-key
Output
The gpg --generate-key command is used to generate a new GPG (GNU Privacy Guard) key pair.
GPG is a widely used open-source software for encrypting and signing data and is commonly used for securing email communications, verifying the authenticity of software packages, and protecting sensitive information.
Provide information
Provide real name and email address
Choose a passphrase
Visualize your gpg key
List the keys
The following lists all the public keys
gpg --list-keys
Output
Just in case you want to list all your private keys, you should run the following command:
gpg --list-secret-keys
Copy your public key
Initialize pass
pass init your-key
It should be something like the following:
pass init DAZF877093FCF01Z4BFA3A0256CD93F8BCFC51B4
Output
Pass is initialized
pass
Output
Open Docker Desktop
Click on sign-in
