I am using below command to install ftp but its showing error message
sudo apt-get install vsftpd
Error Building dependency tree Reading state information... Done E: Unable to locate package vsftpd
Have you tried to resynchronize the package index files from their sources before installing the package?
sudo apt-get update && sudo apt-get install vsftpd
I removed my Singapore droplet mirror and changed mirror from Singapore to Newyork and now it's working.
