Wubi download times are enormous

Asked by dom0410 on 2011-02-25

I am trying to download Ubuntu to my laptop and wish to install it via Wubi. The installer itself downloads promptly but the download times for downloading Ubuntu are enormous, I am typically quoted 430 hours or more! If I try to download the Ubuntu disc image via ubuntu.com my browser quotes a download time of 23 minutes or less. Something seems to be wrong with the servers that Wubi downloads Ubuntu from.

It's hard to say what the problem is. I normally don't let wubi.exe download the Ubuntu Desktop image but do that myself. However, I ran a test on netbook edition the other day and it took only about 30 minutes, and predicted it would take the same amount of time. So whether it's a network problem on your side, on the server side or some other issue ... I can't say.

What release wubi.exe is it? (When you run it, it will show 10.10 in the top centre or 10.04(.x)? If you tell me where you got it from it might help too.

Finally, wubi.exe using a bittorrent client that requires special access to your firewall (it should prompt you to allow access to the python runtime - pyrun.exe). Make sure you allowed this - not sure how it handles it if you don't do this - it might just report excessive wait times.

Hi, thanks for replying to my posting. I am running a Windows 7 laptop with Kaspersky Internet Security 2011. KIS reports that pyron.exe is trusted and thus is not being blocked. Windows Firewall is turned off, as is Windows Defender. I am on a 4.5mbps internet connection connected to the router via ethernet and typically get a download speed of 470KB/s if I try to download the Ubuntu disc image direct from ubuntu.com. I am using the Wubi installer as found here: http://www.ubuntu.com/desktop/get-ubuntu/windows-installer and am trying to download Ubuntu 10.10 via this installer. This issue is also affecting my netbook, also running Windows 7 but with Avira antivirus rather than Kaspersky. Any ideas?

Just testing it now - it started off at 57 hours and steadily went down to 42minutes in a few seconds.

I ran speedtest.net and it reported a connection download speed of 2.57 Mbps from my provider. So if you have 4.5 mbps then I'd expect that to be a little better. I'm running microsoft security essentials as an antivirus. It now says 33 minutes remaining.

So... don't really know what the issue is, but it doesn't look like it's a problem with wubi.exe.

I recommend downloading the image yourself, place it in the same folder as wubi.exe and run wubi from there.

PS... https://wiki.ubuntu.com/WubiGuide#Warning talks about potential grub problems. There isn't a grub update on 10.10 yet, but it's safer to lock these packages.

Interestingly speedtest.net reports that I have a 42.75mbps connection, which is impossible as this is an ADSL connection! Looks like something might be up with my connection. I am doing as you suggested and downloading the image through my browser and saving it in the same place and it is downloading at 466kbps which is what I would expect on this connection. I didn't realise I could simply save wubi and the image in the same place to make that work, thanks for the tip.

Can you help with this problem?
