Looks like postman extension is not suppported on Chrome anymore.
I tried to run it by clicking on icon in chrome://extensions/ page.
I searched in net and found this article:
I removed postman extension and downloaded Postman-linux-x64-7.14.0.tar.gz file
but I stucked at how to install it to follow the instruction?
- Kubuntu 18,
- Google Chrome, Version 79.0.3945.88 (Official Build) (64-bit)
What you downloaded is not a browser extension of any sort, it’s a source code which you will have to compile and install software yourself. I don’t know what build tools Postman requires but you should easily find information either on (K)Ubuntu or Postman websites. It involves work with Terminal and at least, well most likely, working with tools like
configure as well as unzipping and extracting files beforehand.
Edit: although, as I think about it, isn’t Postman already in ubuntu repos? Then you should be able to just download it via Terminal or software centre (don’t know how’s it called in Kubuntu).
