Hm, I've experienced that a few times in the old Nokia SDK. I don't know what is the cause - for me it worked sometimes, but I couldn't pinpoint the root of the problem.

EDIT hey, you don't need to run this as root! User privileges are enough.

My ubuntu is 12.10.
when i write
@./qt-linux-opensource-5.0.2-x86-offline.run@

without sudo it shows me

@Permission denied@

sierdzio

@
sudo chown <your username> qt-linux-opensource-5.0.2-x86-offline.run
sudo chmod 777 qt-linux-opensource-5.0.2-x86-offline.run

start terminal
navigate to the folder with your .run file (eg. cd /home/downloads/)
type: sudo chmod +x qt-linux-opensource-5.0.2-x86-offline.run (Enter)
type: ./qt-linux-opensource-5.0.2-x86-offline.run (Enter - the installation wizard should start)

I wrote your code and show me this

@moslem@moslem-945GZ-CT-M:/media/moslem/0EB40068B400549D$ sudo chown moslem qt-linux-opensource-5.0.2-x86-offline.run
moslem@moslem-945GZ-CT-M:/media/moslem/0EB40068B400549D$ sudo chmod 777 qt-linux-opensource-5.0.2-x86-offline.run
moslem@moslem-945GZ-CT-M:/media/moslem/0EB40068B400549D$

what must I do now?

sierdzio

Run the binary, just like before:
@
./qt-linux-opensource-5.0.2-x86-offline.run
@

Oh, thanks everyone I've found out why it showed me the error. I must use 'sudo' before 'chmod'

"command not found" is (among other things) linux prosaic way about mismatched binary word sizes.

So are you sure you are on a 32bit ubuntu? Or on a 64bit ubuntu with a 32bit set of libraries installed in addition to the normal 64bit ones?
