How can you update an installed package to the latest version in a Linux system?

To update an installed package to the latest version in Linux, package managers are usually used. Depending on the distribution:

• In Debian/Ubuntu and derivatives (apt):

  sudo apt update
  sudo apt install --only-upgrade package_name
  

  Or you can upgrade all packages:

  sudo apt upgrade
  

• In RedHat/CentOS/Fedora (yum or dnf):

  sudo yum update package_name
  # or
  sudo dnf upgrade package_name
  

• In Arch Linux (pacman):

  sudo pacman -Syu package_name
  

Thus, to update a specific package, you need to use the corresponding package manager command with the package name and update option.
