Why can't i execute run-mozilla.sh?

Question

I have downloaded latest version of mozila-firefox from http://tinyurl.com/lm4449e . Try to install it by running following commands.

cd Dowloads
tar xjf firefox-38.0.1.tar.bz2
cd firefox
chmod +x run-mozilla.sh
./run-mozilla.sh

But i am getting an error that "run-mozilla.sh: Cannot execute"

Solution

First you can install it using apt-get, You should update your source list.

sudo apt-get update 
sudo apt-get dist-upgrade

but if you want to install it manually, here what you should do;

Download then extract as you did already

move the extracted folder to /opt

sudo mv firefox* /opt/firefox38

If you already had a previous Firefox version installed in the /opt directory, remove it with the following command:

sudo mv /opt/firefox /opt/old_firefox

Set up symbolic links

sudo mv /usr/bin/firefox /usr/bin/firefox-old

sudo ln -s /opt/firefox38/firefox /usr/bin/firefox

if everything goes well then you can delete firefox-old in /usr/bin and old_firefox dolder in /opt

Did you try bash run-mozilla.sh instead of ./run-mozilla.sh?

You can install it easily by sudo apt-get install firefox

Can you upload the output of cat run-mozilla.sh to paste.ubuntu.com or record it with asciinema?

@Helio: here is the output of cat run-mozilla.sh paste.ubuntu.com/11223005

@NewUSer : I know i can install it by sudo apt-get install firefox but that way i am getting firefox version 28 whereas i want to use the latest version of it. Even i tried to update it after installing version 28, but i did not work out.

What the output of ls?

[Maythux]

do sudo apt-get update and then sudo apt-get dist-upgrade . V 38 is already in sources now

@Helio : here is output of ls paste.ubuntu.com/11223074

[0x2b3bfa0]

Did you try ./firefox or ./firefox-bin?

@NewUSer : As i told you earlier. I tried to update it, but it didn't work out. I tried again and same result :(
