在Ubuntu 9.04即將於4月23日正式發行之際，linux/ubuntu/using-apt-p2p-for-faster-upgrades-from-intrepid-to-jaunty/" target=_blank>這篇博文介紹了一種以P2P升級Ubuntu的方法（如果無法連接到其他節點，仍然能夠從鏡像站點升級），能夠有效的降低鏡像站點的負載，避免在發行日造成網絡擁塞。記住在使用apt-p2p之前需要先禁止所有第三方軟件倉庫。
網站目前下線了，以下是鏡像：
1. apt-get install apt-p2p (Not in Hardy and older repos IIRC... for you late/sporadic upgraders)
2. Back up your /etc/apt/sources.list and then edit the file, s/\/\//\/\/localhost:9977\// (hope I got that right -- Guess I could have just used # or something eh?)
3. Not in the guide: edit /etc/apt-p2p/apt-p2p.conf and set UPLOAD_LIMIT ... just in case. :) You probably have to /etc/init.d/apt-p2p restart after that.
4. apt-get update
5. Then make the update... But it's not time for that yet.
