Well I finally did some research on this strange behaviour and found that Adobe Air itself runs an Auto Update feature every time an Air application is launched, and Ubuntu does it's regular Update Manager checks and finds that the Version of Adobe Air doesn't match it's approved version so it wants to set it back calling it an upgrade.
The two different versions here at the moment are that Adobe has released Version 220.127.116.1130 as it's latest and Ubuntu's authorized latest version is 18.104.22.16890. The good thing is that there is something you can do to stop this crazy Merry Go Round of Upgrades.
I'll start with How to Turn off the Adobe Air Auto Updater. There is no actual configuration interface for Adobe Air but they have provided an installable application that allows you to turn Off and On the Auto Update feature at will. It is a downloaded Air application that can be found at, http://kb2.adobe.com/cps/403/kb403175.html . The second question from the bottom asks,
Is it possible to disable Adobe AIR auto-updates? Yes it is.
Click on the link in the questions answer and download the app called
SettingsManager.air. This process works for any Operating system Linux, Windows, Mac, etc because the app is an Adobe Air application and not an OS based native app.
Install the app by double clicking on the file. You will see the following screen.
Click "Install" to continue.
You'll then get this:
Click "Continue" ... to ... continue.
You'll then get a progress bar for installation followed by a completed message.
That's it then. The Settings Manager app is now installed and if you didn't de-select to place an icon on your Desktop you should now have one called "Adobe Air Settings Manager".
Double click the shortcut to run the application. From there it is as simple as can be.
Click "Disable Updates" to ... Disable Updates. The option then changes to:
In the future to re-enable the updates simply run the app again and choose "Enable Updates" to ... Enable Updates again.
The end result of this is that the Automatic checking for Adobe Air updates will be disabled and the Merry GO Round of Updating will be broken. You will however, be left with the Ubuntu approved version of Adobe Air installed on your PC. While both seem to work just fine in my testing there are complications that could develop down the road from being too far behind the latest Adobe release version.
I hope this tip was helpful and if you found it useful, let me know, leave a comment.
