How do I create a wallpaper package?

How do I create a wallpaper package as a .deb file that will make the wallpapers automatically appear on the Change Desktop Background's 'wallpaper' list?

I think there are wallpaper changer applications available , but have never attempted to write one. I only see Wally in the software center so far. Check here: http://www.liberiangeek.net/2012/03/...cise-pangolin/

Great app, but no thanks
I want to create a wallpaper pack to mass-distribute on the Ubuntu Software Center, so it will have to be one that auto-configures itself in such a way that the computer "sees" them on the first 'Wallpapers' list on the stock wallpaper changer program in Ubuntu.

you'll need a directory called whatever you want to call your package. inside that directory, another directory called DEBIAN, and another called usr. inside usr, another directory called share. inside share, another called backgrounds. inside backgrounds, your wallpaper.

inside the DEBIAN directory, 2 files: a text file called "control" and a "postinst" script.

this is an example of a control file:

Package: package name
Priority: optional
Section: misc
Maintainer: your name <your@email>
Architecture: all
Version: version number
Depends: whatever it depends on.
Description: a brief description of what your package includes or does.

notice the blank line at the end. it's important.

the postinst script will just tell the system what to do with the included files. here's an example:

#!/bin/bash

chmod a+r /usr/share/backgrounds/your-awesome-wallpaper

exit 0

once you have this, you'll need to change ownership of the directory. suppose you have it on /home/you/wallpaper

you would:

sudo chown -R root.root /home/you/wallpaper

once ownership has been given to root, you just build the package.

sudo dpkg -b /home/you/wallpaer wallpaper.deb

and that's it.

it sounds and looks more complicated than it really is.

Thanks
I'll probably need some more help, but if and when I do, I'll hit you up! Thanks

What would I put for "depends"? "Section"?

[angry_johnnie]

well, if it's just a set of wallpapers, i guess you could leave it blank it's just images, so it doesn't really need anything other tan a display.

If I have multiple pictures, how would I design the Postinst file? The postinst file is confusing me

[angry_johnnie]

well, the postinst script just makes sure that everything is set up with the right permissions once installed. you want to make sure the user has read permissions on all the images.

so, for example, if your wallpapers are called image1, image2, image3, and so on, you would have to do as follows:

#!/bin/bash

chmod a+r /usr/share/backgrounds/image1
chmod a+r /usr/share/backgrounds/image2
chmod a+r /usr/share/backgrounds/image3

exit 0

this way you'll ensure that all users have read permissions on the images. otherwise they won't be able to see them, even if they're on the correct directory.

Okay, now if there is a space in the file name, do I put a "_" (underscore) or just keep a space?
