I see you're new to the forum. Welcome! Judging from your post you must have missed some points that were discussed earlier in this thread. Please allowe me to summarize:
Johan wrote:You can also simply install Ardour from the linux distribution
This is, of course, correct!
Johan wrote:this is just from ardour itself and is simply supported.
This is not completely accurate. Most distributions do not distribute the binaries provided from the Ardour site, but build Ardour themselves. Of course they build Ardour from the same sources, but they might apply some patches to integrate it better with the distribution, or fix problems due to different library versions.
These versions are often very reliable, but unfortunately in the past there have also been distributions who made mistakes while building/adapting Ardour, or shipped very old versions. For that reason, the Ardour developers have made it clear that they only promise support for the official builds from their website, and not for rebuilds from distributions. For support for rebuilds, you can of course try to see if you can get help on this forum, or use the bug tracker of your distribution.

No problem! If you want me to explain the above in your native language don't hesitate to let me know!
