Hi @Eduardo12l,

It looks like I need to update steps #1 and #2 in the documentation.

Here's a quick version:

1. Go to http://download.qt.io/official_releases/qt/5.10/5.10.0/

2. Choose a random file and click "Details" under "Metadata". At this stage, it doesn't matter which file you choose; we simply want to check the servers' download speeds.

(Steps #3 onwards are unchanged)

. PS: Is it useful only for linux?

No, it works for Windows and macOS too. The screenshots just used Linux as an example.

@JKSH it failed, the installation stops anyway. Or maybe i dont understand what you are trying to say in step 5 when says "select"

Did you get a good, consistent download speed? At what stage does the installation stop?

In step #5, "select" means choose a mirror from the drop-down menu. For best results, choose a mirror which gave you a consistently high download speed in step #3.

There is no guarantee that the first mirror that you try will work, so try a different one.

If you still don't have any luck, try installing Qt via the offline installer instead from http://download.qt.io/official_releases/qt/5.10/5.10.0/ (If you're on Windows, get qt-opensource-windows-x86-5.10.0.exe)

The latest version, 24 Jan 2018 is V1.1.0. I downloaded and am trying the steps but the QT pages have changed. I try entering some of the URL directly such as:
www.qt.io/download-open-source/
But Chrome changes it to
www1.qt.io/download-open-source/
notice the www1, and gives me a page not found.

Yes, I need to update the instructions. For now, scroll up to https://forum.qt.io/post/437282 (it's 3 posts above yours)

You can use the x86 (32-bit) installer. The 32-bit installer can install 64-bit packages.

Fiddler-proxy with hostname-replacing helped me download from fastest mirror in my country.
I try this tool, but Qt Installer still download from download.qt.io (only local rep was enabled)

I past all links from this page http://download.qt.io/official_releases/online_installers/qt-unified-windows-x86-online.exe.mirrorlist in DownloadMaster and find the fastest server in Kazakhstan is mirrors.dotsrc.org

In Qt Installer settings I add proxy 127.0.0.1:8888
In Fiddler I change Customize Rules "OnBeforeRequest":

if (oSession.HostnameIs("download.qt.io") && oSession.PathAndQuery.StartsWith("/online/"))
{
	oSession.hostname = "mirrors.dotsrc.org";
	oSession.PathAndQuery = oSession.PathAndQuery.Replace("/online/", "/qtproject/online/");
}

downloading speed changed from 300Kb/s to 10MB/s

@Geograph I want to try this method, unfortunately there's no fiddler-proxy on linux. There's only fiddler everywhere but it's still in beta so I don't know if there's hostname-replacement capabilities yet. Do you know any linux (mint) alternative?

The tool didn't work for me, and it broke my Maintenance Tool. After reverting the settings, I get a message that the Maintenance Tool "appears to be older than 3.0.2".

And why should I have to use this tool in the first place, when Qt has been aware of this issue for so many years? I was getting useless speeds from a Japanese mirror, so I had no alternative.

I've had this issue with the Qt online installer for several years on Windows. It almost never works and I think Qt has one of the worst install experiences. To make it even worse they have recently removed the offline installers. At the moment I have no way to install Qt on Windows unless I build it my self from sources.

Well, those are now only available for users with commercial license.
I'm too not happy with recent changes.

Personally I never had issues with online installer, but I know that many users have such issues and it is really pity that those are still not fixed. In most cases the issues are caused by slow/not reachable mirrors, but the official installer does not provide the possibility to select another mirror from a list.

I have been trying daily since 12th this month. After posting here yesterday it now works. Coincidence or not, I don't know :)

After a long journey, the official Qt Online installer has now added support for mirror selection. A big thanks to the engineers at the Qt Company: https://wiki.qt.io/Online_Installer_4.x#Selecting_a_mirror_for_opensource

Thank you also to everyone who used the Qt SDK Repo Chooser over the years!
