I downloaded postman tar from the official website and extracted the files, just like I did it the exact same way when I was using Ubuntu 16.04. Extracting is working but When I want to launch the application by double clicking the executable, it is not responding. While in 16.04 it would then launch Postman. I'm not getting any errors, just no reaction. I tried the x64 and x86 versions but that made no difference.

    Postman-linux-x64-6.0.10.tar.gz. No guarantee that an executable can be clicked / double clicked with any OS. .... ... Please do the command ./Postman In a terminal → If any errors, they should appear as text. ( I get this : "ORM initialization successful", etc.) – Knud Larsen May 3 '18 at 12:39
  • Launching in a terminal gave me the error in the answer that was provided. I can now launch it in terminal and by clicking. – SebastienPattyn May 3 '18 at 13:07

I had the same problem on a clean 18.04 install, the library libgconf2-4 could not be found.

Try sudo apt install libgconf2-4, it should solve your problem.


Slight change to the answer provided by @Stanko worked for me.

Try adding hypen(-) in between libgconf and 2

sudo apt install libgconf-2-4

    Worked for me on Ubuntu 19.04. Thanks – j-bin May 22 '19 at 22:03

In my case previous solution wasn't enough. I had to run:

killall _Postman
killall Postman

This will terminate all lingering Postman processes

    Thanks this worked for me! Postman client was freezing and refusing to open new collections – Matti Feb 12 at 16:45

After sudo apt install libgconf2-4 I also needed to give permissions to the /home/yourusername/.config/Postman/ folder. Then it worked like a charm.

  • I have no Postman directory in ~/.config – JL_SO Feb 18 '20 at 13:34
