-- Building the script to keep it up to date

Caution: Do not initialize your script or set your cron job until the initial download is done!

Open an editor (vi, pico, or gedit) and save the following code as /usr/local/bin/ubuntu-mirror-sync.sh

vi /usr/local/bin/ubuntu-mirror-sync.sh

# Mirror Synchronization Script /usr/local/bin/ubuntu-mirror-sync.sh
## Version 1.01 Updated 13 Feb 2007 by Peter Noble
## Point our log file to somewhere and setup our admin email
log=/var/log/mirrorsync.log

adminmail=admin@my.domain
# Set to 0 if you do not want to receive email
sendemail=1

# Subject is the subject of our email
subject="Ubuntu Mirror Sync Finished"

## Setup the server to mirror
remote=rsync://archive.ubuntu.com/ubuntu

## Setup the local directory / Our mirror
local=/media/mirror/ubuntu

## Initialize some other variables
complete="false"
failures=0
status=1
pid=$$

echo "`date +%x-%R` - $pid - Started Ubuntu Mirror Sync" >> $log
while [[ "$complete" != "true" ]]; do

    if [[ $failures -gt 0 ]]; then
            ## Sleep for 5 minutes for sanity's sake
            ## The most common reason for a failure at this point
            ##  is that the rsync server is handling too many concurrent connections.
            sleep 5m
    fi

    if [[ $1 == "debug" ]]; then
            echo "Working on attempt number $failures"
            rsync -a --delete-after --progress $remote $local
            status=$?
    else
            rsync -a --delete-after $remote $local >> $log
            status=$?
    fi
    
    if [[ $status -ne "0" ]]; then
            complete="false"
            (( failures += 1 ))
    else
            echo "`date +%x-%R` - $pid - Finished Ubuntu Mirror Sync" >> $log

            # Send the email
            if [[ -x /usr/bin/mail && "$sendemail" -eq "1" ]]; then
            mail -s "$subject" "$adminmail" <<OUTMAIL

done

exit 0

Use Cron to keep the mirror up to date

crontab -e

15 21 * * * /usr/local/bin/sync-ubuntu-mirror.sh > /dev/null 2> /dev/null

Publish the mirror on the Apache server

cd /var/www/

ln /media/mirror/ubuntu -s

systemctl restart apache2
