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

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

@stillru That is a very good idea, and it is probably the best way, thanks! :D
I edited it a bit to use a different scheme, day of year looks nicer in my opinion and hour could be useful.
Also PRs do not exist for gists, but I added you (and everyone else who helped in one way or another) to the new contributors part of the README.

Other than that:

  • targetName is now actually used as target name
  • I fixed the issue where dpkg-deb complains about the Optional field
  • I added licensing information (MIT), which could be useful

I hope everything will work now : )

@fakhamatia I don't get that message on my system (Debian Testing), but it looks like it is caused by the fact that the download and build is done by your current user instead of the _apt user. And in my opinion the build should be done by the current user.

I could add a check to see if the _apt user exists and chown the package if it does. But since the install succeeds and the loglevel is notice, I think the best way for now is to just ignore it.
