I am looking for a tutorial creation software like WINK in Ubuntu 11.10 (WINK is not in the repositories). Is there anything I can use, that is easy to learn, exports to flash, and possible has audio capability, and of course works in Ubuntu versions (current and upcoming)?
There are different applications to record screencasts under Ubuntu. They may not allow creating flash videos directly, but usually you can convert the screencast to flash in a separate step.
Here's a list of applications that are available via apt:
You may even use VLC Media Player to record screencasts.
There seems to be almost no application that allows for creating interactive tutorials or screencasts. There's only one project named Salasaga (see also Salasaga on Launchpad) that looks very promising, but it's still in it's alpha stage.
