Answer 1

Problem

doctl is not able to find docker because snap binary path is /usr/snap/bin and docker binary path is /usr/local/bin/

so somehow connection between them is broken

THIS IS MY CUSTOM SOLUTION TO MAKE IT WORK :

Step-1 : Uninstall doctl and Refresh env path

#sudo snap remove doctl

Step-2 : Install doctl using latest package

wget https://github.com/digitalocean/doctl/releases/download/v1.17.0/doctl-1.17.0-linux-amd64.tar.gz
curl -sL https://github.com/digitalocean/doctl/releases/download/v1.38.0/doctl-1.38.0-linux-amd64.tar.gz | tar -xzv
sudo mv ~/doctl /usr/local/bin

(optional)Step ? : Fix path Problem if doctl not found then fix it using Symbolic Link

ln -s /usr/local/bin/doctl /usr/snap/doctl

Step-3 : Run docker login command

#doctl registry login

**IF getting error related to x11 then run command below and try Step-3 **

sudo apt update 
sudo apt -V install gnupg2 pass

#doctl registry login

login successfully
