I am wondering who I need to get in touch with to find out information regarding books in the Ubuntu Software Centre. What are the requirements? Does Ubuntu get a percentage regarding the sale (like apples app store) and who do we need to submit it to? I am interested in doing manuals and novels for the Ubuntu Software Centre since I wish to support the idea. Thanks in advance!
For anyone that wishes to publish an application on the Ubuntu Software Center simply go to software-center.ubuntu.com and submit your application!
Also have a look at developer.ubuntu.com. The main page shows:
1 thing: it looks like books in USC are from well known companies and/or long time running online magazines. You probably need to have several issues ready for submission to show you are dedicated.
The easiest way to get your books, magazines, games, applications, etc into the Ubuntu Software Center is to go to https://myapps.developer.ubuntu.com, register, and submit a new application. The developer agreement is found at https://myapps.developer.ubuntu.com/dev/tos/ and should answer your questions.
IF you do have questions about submissions or anything else related to paid applications/content on the Ubuntu Software Center, simply reach out to john dot pugh at canonical.
