I am trying to set up Node.js and NPM on a Ubuntu 14.04 machine but am having some trouble. On my first try I kept getting EACCES errors when trying to install packages(sometimes even with sudo ), so I completely uninstalled node and npm. Now I'm trying to figure out how to install them in a way that won't require me to run everything sudo and won't give me EACCES errors.

Today (2015-05-02) I upgraded my Linux system via apt-get update and apt-get upgrade whereas mysql, mysqladmin and a lot more packages have been updated. The mysql-server-5.5 runs and I can login and do all the typical database operations but when I type: user@ubuntu:~# mysqladmin proc I get the following error: mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user 'root'@'localhost' (using password: NO)' Formerly I could solve this issue by simple setting the mysql root password new. This does not solve the issue anymore: user@ubuntu:~# sudo dpkg-reconfigure mysql
