Reflector is a script which can retrieve the latest mirror list from the MirrorStatus page, filter the most up-to-date mirrors, sort them by speed and overwrite the file /etc/pacman.d/mirrorlist.

Installation

Install the reflector package.

Usage

Warning:
  • /etc/pacman.d/mirrorlist will be overwritten by default. Make a backup before running reflector.
  • Make sure the resulting /etc/pacman.d/mirrorlist does not contain entries that you consider untrustworthy before syncing or updating with Pacman.

To see all of the available commands, run the following command:

# reflector --help

Examples

For the below examples, a country-sorted list can be retrieved with curl:

# curl -o /etc/pacman.d/mirrorlist https://www.archlinux.org/mirrorlist/all/

Filter the first five mirrors, sort them by download rate and overwrite the file /etc/pacman.d/mirrorlist:

# reflector --verbose -l 5 --sort rate --save /etc/pacman.d/mirrorlist

Verbosely rate the 200 most recently synchronized HTTP servers, sort them by download rate, and overwrite the file /etc/pacman.d/mirrorlist:

# reflector --verbose -l 200 -p http --sort rate --save /etc/pacman.d/mirrorlist

Verbosely rate the 200 most recently synchronized HTTP servers located in the US, sort them by download rate, and overwrite the file /etc/pacman.d/mirrorlist:

# reflector --verbose --country 'United States' -l 200 -p http --sort rate --save /etc/pacman.d/mirrorlist

Systemd Service

/etc/systemd/system/reflector.service
[Unit]
Description=Pacman mirrorlist update

[Service]
Type=oneshot
ExecStart=/usr/bin/reflector --protocol http --latest 30 --number 20 --sort rate --save /etc/pacman.d/mirrorlist

Then starting reflector.service will update your mirrorlist.

To update your mirrorlist every time your computer boots you can enable the following service definition.

/etc/systemd/system/reflector.service
[Unit]
Description=Pacman mirrorlist update
Requires=network-online.target
After=network-online.target

[Service]
Type=oneshot
ExecStart=/usr/bin/reflector --protocol http --latest 30 --number 20 --sort rate --save /etc/pacman.d/mirrorlist

[Install]
RequiredBy=multi-user.target

Make sure you activate the appropriate services so that network.target really reflects your network status.

Systemd Timer

If you want to run reflector.service on a weekly basis:

/etc/systemd/system/reflector.timer
[Unit]
Description=Run reflector weekly

[Timer]
OnCalendar=weekly
RandomizedDelaySec=12h
Persistent=true

[Install]
WantedBy=timers.target

And then just start the reflector.timer.

AUR package

Install the reflector-timerAUR package to run reflector daily, or install the reflector-timer-weeklyAUR to run it weekly.

reflector-timer

The default configuration is:

/usr/share/reflector-timer/reflector.conf
AGE=6
COUNTRY=Germany
LATEST=30
NUMBER=20
SORT=rate

To override this configuration, edit /etc/conf.d/reflector.conf:

/etc/conf.d/reflector.conf
COUNTRY=US

Be sure to enable reflector.timer.

reflector-timer-weekly

The default configuration is:

/etc/reflector.conf
--save /etc/pacman.d/mirrorlist
--country China
--sort rate

Each line (except that begins with '#') should be valid reflector option.

Be sure to enable reflector.timer.
