Study Notes
Service Stations and Their Operating Systems
- Service stations and their operating systems are covered
- Software packages are discussed
GNU/Linux Software Packages
- Each GNU/Linux distribution comprises a collection of software packages
- A package can be viewed as a specific distribution component
- Examples include video encoding libraries (e.g., libvorbis), font sets, video, audio, and office applications
Package Management Systems (PMS)
- Ubuntu employs the apt program for package installation and management
- Users are provided with user-friendly tools for installing and managing software packages
- Key tools include the Ubuntu Software Center, aptitude (command-line), and synaptic (GUI)
PMS Functions
- Manage dependencies of installed packages
- Guarantee authenticity of package sources
- Install, remove, and update package versions
- Group packages according to interest groups
Package Management System Functioning
- A package installation request initiates the process
- The PMS identifies the package and its dependencies
- The PMS retrieves required packages
- PMS installs and configures packages, providing recommendations
- The user employs the software
Software Packages in Linux Distributions
- .deb files are used in Debian distributions; APT is the management system
- .rpm files are used in Red Hat distributions; YUM is the management system
- Portage is used for Gentoo distributions; Emerge is the management system
- Homebrew is used for Mac OS and Cygwin for MS Windows.
Package Management Tool dpkg
- Ubuntu uses the Debian package management system (dpkg)
- Basic operations include installing and removing .deb files
- dpkg does not support downloading packages from the internet
- dpkg -l command lists installed packages
APT Command-Line Interface
- APT (Advanced Packaging Tool) is used for downloading and installing packages
- Key commands include apt (apt-get), apt-cache
- Examples include updating package lists (apt update), upgrading packages (apt upgrade), searching for packages (apt-cache search), displaying package details (apt-cache show mc), and installing a package (apt install).
- Users can find and install the Java JDK version 17
APT Features
- Allows for package installation, removal, and updates
- Manages dependencies between packages
- Provides information about selected packages
- Manages repository signatures
- Key catalogs & configuration files include /etc/apt/sources.list and /var/cache/apt/archives/
APT Tool Shells
- Tools like aptitude, Synaptic, and the Ubuntu Software Center provide user interfaces to interact with APT
Ubuntu APT Repositories
- Software repositories are categorized based on FOSS principles
- Types include Main (official), Restricted (official, but potentially licensed), Universe (community-maintained), and Multiverse (non-free).
PPA - Personal Package Archives
- PPAs are used for obtaining newer software versions (pre-release or development)
- Safety measures, such as verifying PPA popularity and update frequency, reduce risks
- Examples for finding and adding a PPA include visiting launchpad.net and using the command sudo add-apt-repository
Building Software from Source Code
- Source code installation involves downloading source code, running configuration scripts, compiling it (make), and installing the resulting software.
- Examples include using commands like git and make
- This method permits customization and installation of very specific packages
