Slow downloads with the online installer? Try this tool

JKSH

FINAL UPDATE: The Qt Installer Framework 4.0.1-1 now officially supports mirror selection. Please use that instead.

See https://wiki.qt.io/Online_Installer_4.x#Selecting_a_mirror_for_opensource

UPDATE: Unfortunately, the Qt SDK Repo Chooser is no longer usable. Qt IFW 3.0.2 changed its internals to only use server-provided URLs.

Alternative 3rd-party installers can be used instead (Note that I have not tried them myself):

Hi all,

Some users around the world get slow downloads and/or frequent disconnections because they are assigned a poorly-performing mirror. We are waiting for features that work around poor mirror performance, such as the ability to choose your mirror, and the ability to resume downloads.

In the meantime, if you (or someone you know) are experiencing difficulties with the online installer, try the Qt SDK Repo Chooser. It sets up a repository locally that points to a mirror of your choice, which would hopefully give you a better download experience.

So far, I've provided a Windows build. I have successfully run the Windows build on Ubuntu 14.04 through Wine in Windows XP mode, although the repository path needs to be converted from a Windows path to a Linux path.

If you'd like to contribute another build (especially an OS X one), I'd be happy to host it on the GitHub downloads page.

Hi,

Where should I send you the dmg ? :)

JKSH

Thanks SGaist! I've PM'ed you the details.

When adding the local repo to User-Defined repos, should I disable all the entries in "Default Repositories"?

You should disable "Qt <platform> online root repository" (for example, "Qt Windows-x86 online root repository"). However, don't disable anything else.

I still have problem with download QT. Installer stood at 18-20% with error - some path and "Connection time exceeded". It doesn't matter which repository I choose - always same problem :( Any ideas?

You could try the offline installer instead: http://download.qt.io/official_releases/qt/5.10/5.10.0/

Hi @Eduardo12l,

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

Here's a quick version:

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