Final answer:
Package repositories are collections of software and source files used by package management systems to install, update, and remove software on a Linux system.
Step-by-step explanation:
The statement is True. Package repositories are indeed collections of software and source files that are used by package management systems on a Linux system. These repositories provide a centralized location where users can find, install, update, and remove software packages. Examples of package repositories on Linux include Debian's APT repositories, Fedora's Yum repositories, and Ubuntu's Snap Store. Package management systems, such as APT (Advanced Package Tool), Yum, or Zypper, rely on these repositories to provide a centralized and organized way to distribute and manage software packages.
