Understanding Repositories

Official Repositories

Main repositories:

  • core: Core packages
  • extra: Extra packages
  • community: Community packages
  • multilib: 32-bit packages

Repository Configuration

Edit pacman.conf:

# Edit config
sudo vim /etc/pacman.conf

Mirror Configuration

Using Reflector

Generate mirrors:

# Install reflector
sudo pacman -S reflector

# Generate top 10 mirrors
sudo reflector --country "United States" --latest 10 --sort rate --save /etc/pacman.d/mirrorlist

# Update
sudo reflector --latest 20 --sort rate --save /etc/pacman.d/mirrorlist

Manual Mirror Selection

Edit mirrorlist:

# Edit mirrorlist
sudo vim /etc/pacman.d/mirrorlist

# Uncomment preferred mirrors
# Order matters - first is tried first

Repository Priorities

Priority Configuration

Set priorities:

# Edit pacman.conf
sudo vim /etc/pacman.conf

Example:

[core]
Include = /etc/pacman.d/mirrorlist

[extra]
Include = /etc/pacman.d/mirrorlist

[community]
Include = /etc/pacman.d/mirrorlist

Custom Repositories

Add Custom Repository

Add repository:

# Edit pacman.conf
sudo vim /etc/pacman.conf

Add:

[custom]
Server = https://example.com/repo/$arch

Update:

# Update database (use -Syu for full update)
sudo pacman -Syu

# Note: -Sy without -u can cause dependency issues
# Only use -Sy when specifically checking package availability

Troubleshooting

Slow Downloads

Change mirror:

# Use reflector
sudo reflector --country "United States" --latest 10 --sort rate --save /etc/pacman.d/mirrorlist

# Update
sudo pacman -Syu

Repository Errors

Fix errors:

# Update package database and upgrade (recommended)
# Note: Always use -Syu together to avoid dependency issues
sudo pacman -Syu

# Clear cache
sudo pacman -Sc
