Ubuntu: Failed to execute child process? Anyone know a fix for this?



Question:

I changed something that I did not mean to change and now everytime I try to open Firefox it says:

could not launch application, failed to execute child process "firefox" (No such file or directory).  

Aybody know a fix for this? I am using Backtrack 5 r3 with Gnome, which is based off of ubuntu 10.04.


Solution:1

You have lost the binary file of Mozilla firefox. By lost, I mean it has either been renamed/replaced/moved/deleted; any of these. If you do not know what has actually happened and can afford to lose your firefox data(browsing history, saved passwords, etc.) then the easiest way to procure the binary is to re-install the complete package.

To re-install, open a terminal and type:

sudo apt-get purge firefox  sudo apt-get install firefox  


Solution:2

This can be solved by not running the application as a root user, therefore create another user and launch the application from there it works fine.
