Issue in QT 5.0 installation on Ubuntu 12.04

Asked by Himanshu

Dear All,

I am trying to install QT in ubuntu 12.04. And I am refering the belwo link for the same.

http://www.wikihow.com/Install-Qt-SDK-on-Ubuntu-Linux.

I am using 32 bit Ubuntu version.

I am facing the problem in below steps. ( Please refer to the link for the steps)
 6th Step
sudo -s chmod u+x QtSdk-offline-linux-x86_64-v1.2.1.run ( What is we trying to acheie through this command?) and I am getting
the error "Unable to resolve host"

8th Step
Why are we changing the path?

9th Step
"Unable to resolve host local machine"

Moreover, System update manager doesnt show the option of QT 5 but on QT side it is being releases.

In short, I suspect that these installation steps are not correct. Kindly help me in installing the QT on ubuntu.

Please let me know in case more information is required.

you have been messing with your hostname. The name you have setnis not in /etc/hosts so the OS cannot resolve it's own name to 127.0.0.1

Run:
hostname

Make a note of the hostname then run:
gksudo gedit /etc/hosts

Change the current lines with 127.0.0.1 and 127.0.1.1 to the system hostname, save the new file, close gedit and reboot

Can you help with this problem?
