Hi,

Looks like you have some connectivity issues.

Did you try to use a different mirror ?

[JKSH]

To clarify @SGaist's comment, see https://wiki.qt.io/Online_Installer_4.x#Selecting_a_mirror_for_opensource

[nadimnadaf]

@SGaist Yes We try multiple times with different networks.

Hi, Qt 6.3.1 requires Ubuntu 20.04 or later, that could be the reason for the failed download.

Good catch. The online installer, and the latest Qt Creator that it provides, currently doesn't work properly on Ubuntu 18.04: https://bugreports.qt.io/browse/QTCREATORBUG-26167

But this shouldn't cause the "connection closed" errors.

@hskoglund OK , Then which version we needs to install to support the Ubuntu 18.04

• Qt 5.15
• Qt Creator 5.0

Like that number of errors will show.
So please, which version we needs to install

The screenshot shows that you are trying to install Qt 6.3.1. This cannot work on Ubuntu 18.04, as @hskoglund said.

Install Qt 5.15 instead. If you see errors about sdktool when you try to install Qt 5.15, you can click "Ignore".
