1.) First of all, before starting to run any installation on Ubuntu it would be nice to update the package and repository first, please use the following command. 2.) Then do the command for proftpd installation. 3.) Once you are done, you can actually use FTP directly, try opening it in your browser by typing ftp: // ip-you, or use third-party software such as FTP Client, like FileZilla. Your username and password are your default Ubuntu username and password, with default port 22. 4.)
