I am testing app in kubuntu v25.04 running in a vm but have hit a problem. This is what happens:

• install using the command: apt install ./AstroPixelProcessor-2.0.0-beta38-Linux-DEB-64-but.deb
• startup APP
• set working directory
• click "lights" button - APP dies and disappears from the screen
• restart APP - now hung up - all buttons are greyed out and the program appears to be running in a loop at high cpu

Is this a known problem?

Is APP supported on kubuntu?

Did I install correctly?

Running from the cmd line shows this:

help! regards, Richard

I don't usually go for non-LTS distros, but when I do I do regret things. This release of Ubuntu is only an interim to get me to 25.04, but that's currently unavailable so now I'm stuck with an inabilty to process APP on Ubuntu 24.10

I've tried on APP 2.0.0 Beta35 and Beta36.

I noticed an APP-startup.dat file gets created. Not sure if this helps (or at least narrow down the stage where the problem is).

-rw-rw-r-- 1 kevinj kevinj 12288 May 4 12:01 APP-startup.dat
kevinj@jupiter:~$ strings APP-startup.dat
12:01:25 - started Astro Pixel Processor
12:01:25 - setup OS, arch, DPI variables
kevinj@jupiter:~$

I am trying out APP but I am getting an error popup when calibrating masterflat. See error below:

Encountered error in module:
LightFrameCalibration

Error message:
java.lang.ArrayIndexOutOfBoundsException: Index 1 out of bounds for length 1

Cause:
Index 1 out of bounds for length 1
fP.a(FrameDataCalibration.java:992)
fP.doInBackground(FrameDataCalibration.java:47)
java.desktop/javax.swing.SwingWorker$1.call(Unknown Source)
java.base/java.util.concurrent.FutureTask.run(Unknown Source)

The process just stalls and I can't do anything but close the program.

I am using Arch and APP 2.0.0-Beta26

I have some leftover hardware, and I am considering reusing it dedicated to APP stacking, especially for large mosaics. 

It`s a first-gen Threadripper with 16 cores, 64GB DDR4, and a GeForce RTX 3080 with 2x 512GB NVME SSD.

Two Questions:

1. What would be the best Linux distribution to run APP? Or would Windows work better?
2. Would it be worth to upgrade the RAM to 128GB for better performance or larger mosaics?

I have a lot of experience with Windows and Mac but just basic knowledge of Linux. So, any hint would be highly appreciated. 

Thank you!

Best regards.
