Step 1
If any version of postman is installed we need to remove it
sudo rm -rf /opt/PostmanStep 2
This will install postman to /tmp directory and move it to /opt/ directory.
tar -C /tmp/ -xzf <(curl -L https://dl.pstmn.io/download/latest/linux64) && sudo mv /tmp/Postman /opt/Step 3
Create a desktop file
sudo tee -a /usr/share/applications/postman.desktop << END

Gnome 46 can be a bit picky with desktop entries. Running update-desktop-database and reloading the shell usually fixes icon issues. For what it’s worth, some people avoid these setup steps entirely by using tools like Apidog that work out of the box on Linux.
