How to Update Arch Simple Step-by-Step Instructions for Beginners

Before updating, ensure critical data is backed up and no important processes are running. Verify sufficient disk space with df -h.

Preparation

• sudo pacman -Syu --noconfirm reflector
• sudo reflector --latest 20 --sort rate --save /etc/pacman.d/mirrorlist
• sudo pacman -S archlinux-keyring

Update System

• Refresh Package Databases: sudo pacman -Syy
• Perform Full System Upgrade:
  sudo pacman -Syu --overwrite=''

  

  Review the update list carefully before confirming.

Post-Update Tasks

• Remove Orphaned Packages:
  sudo pacman -Qtdq sudo pacman -Rns -
• Clear Package Cache:
  sudo paccache -r

Troubleshooting

If encountering signature errors:

• sudo rm -r /etc/pacman.d/gnupg
• sudo pacman-key --init
• sudo pacman-key --populate archlinux

Reboot if kernel or critical system components were updated: sudo systemctl reboot
