Notes on computer management and usage

Author: Modified by Elliott Abe, Originally written by Takafumi Arakaki

Software installation

Prefer using Ubuntu's package manager (sudo apt install <PACKAGE>, sudo dpkg -i ... etc.) as much as possible. There has to be a very very VERY good reason when using other kinds of installation methods (e.g., sudo pip install <PACKAGE>, sudo sh <INSTALLATION_SCRIPT>).

Please contact me whenever you think you need software which is not in Ubuntu's official repository. -- Elliott

User management

• Add user named <USER_NAME>: sudo adduser <USER_NAME>
• (Optional) Grant a user <USER_NAME> the permission to do sudo: sudo usermod -aG sudo <USER_NAME>
