Is there any Adobe readers that I can use for ubuntu?
Reader 9 was the last available release. Long out of date and unsupported, it might happen to work if you can find it. But Linux systems include PDF readers aplenty.
Adobre pls deploy Linux version for your product - this is not difficult
If it's not difficult then you can do it yourself... The PDF format is an open one (ISO 32000) and anyone can write an application to read, display and even edit PDF files. When you start working on it you'll find out exactly how much not difficult it is (hint: the document describing the PDF file format is around 1000 pages of an extremely technical nature, even before getting into PDF v2.0 territory). Good luck!
Oh, and I'm sure you'll be happy to share the application for free with the rest of the world once you're done, right?
Doesn't Linux have great open source PDF viewers already? What's wrong with them?
