Ubuntu, installing Qt 5.1.1

I just installed windows 8, Ubuntu twice because it failed the first time somehow (couldn't start from grub).

However, now everything works fine. The only exception is that I cannot install Qt 5.1.1.

I downloaded the latest QT version from their homepage for Linux 64 bit (around 415 MB). The only problem is, I cannot start the application. I checked this in the permissions of the installer.

"Execute : (Checked) Allow executing file as program"

It still won't start. I tried to open it with terminal and sudo. This is the output :

david@lw-gd-45:~/Downloads$ sudo
./qt-linux-opensource-5.1.1-x86_64-offline.run
./qt-linux-opensource-5.1.1-x86_64-offline.run: 3:
./qt-linux-opensource-5.1.1-x86_64-offline.run: Syntax error:
Unterminated quoted string

What am I doing wrong? Worked fine in Linux mint...

Are you sure the file is not broken? Try checking the MD5:md5sum qt-linux-opensource-5.1.1-x86_64-offline.run

According to: the MD5 should be: f2caba7912b42d0d07fed6436252acdb

If the MD5 isn't correct try downloading the file again.
