As a typical Ubuntu release, I’m predicting the servers being hammered with traffic as Canonical releases their (at least imo) most stable release yet: Karmic Koala. So for a little bit of fun, I wrote a script to poll the server for the final release whenever it becomes available. This will check every 15 minutes to see if it is available, download the file and quit. Modifications can be made to resume the download (provided their servers support it, and I’m pretty sure they do) but I didn’t have the time to add that. This requires the python-urlgrabber package to be installed.
import os.path import time import urlgrabber from urlgrabber.progress import TextMeter progress = TextMeter() release = 'ubuntu-9.10-desktop-amd64.iso' server = 'http://releases.ubuntu.com/releases/9.10/' print "Downloading %s%s" % (server, release) while not os.path.exists(release): try: urlgrabber.urlgrab(server release, progress_obj=progress) except: print "Not available yet...Checking again in 15 minutes" time.sleep(900) # Wait 15 minutes before checking again
