Postman Debian Package Builder

Usage

Simply run the one of the following commands in your terminal and it will download the latest Postman version, build a .deb package and ask you if you want to install it.

if you have curl:

curl https://gist.githubusercontent.com/SanderTheDragon/1331397932abaa1d6fbbf63baed5f043/raw/postman-deb.sh | sh

If you do not have curl:

wget -O - https://gist.githubusercontent.com/SanderTheDragon/1331397932abaa1d6fbbf63baed5f043/raw/postman-deb.sh | sh

Issues

Building Problems

• chrisbjr: missing -e in some shells
• cyfrost: -e not working with direct command
• fakhamatia: dpkg-deb not building with wrong permissions

Missing Dependencies

• jveillet: gconf2
• kagurazakakotori: libgtk2.0-0 and libcanberra-gtk-module
• wirwolf: desktop-file-utils

Installation Problems

• maxgalbu, R0nAk: desktop file not installing

Upstream Changes

• emamut: changed icon path
• mikiTesf: changed tarball name from Postman to postman
• stillru: changed tarball name to one without version information
• 0xjams: changed from GTK 2 to GTK 3

---

Ideas

• xlmnxp, cyfrost, Killea: direct curl command (at the top)
• cyfrost: version check before building
• n8eloy: -y flag for apt install
• stillru: using date as version
• 0xjams: support for ARM64

Thank you @SanderTheDragon. I'm find postman fix cursor very long until I found it this repo.

I added a check so that it downloads the right version depending on the architecture. I also removed gconf2 as a dependency, and it seemed to work just fine.

https://gist.github.com/0xjams/d8ca3c2448e97bfae1cf1812d6e7f9ee

@0xjams Thanks for these improvements!

I moved the architecture check to the top, so the date/version is checked for the correct architecture (I would expect that they are the same, but just to be sure).
I also checked the dependencies, and it seems like it now depends on GTK 3 instead of GTK 2, so gconf2 is not needed anymore.

Thanks for it!!
