Have had no issues using KStars/Ekos on my Stellarmate OS 1.5.5 Raspberry Pi 4. Today I booted my device and found KStars crashing upon startup. Using the Ekos Debugger on the desktop, I logged the errors below. My system is fully up to date (sudo apt-get update; sudo apt-get upgrade; sudo apt-get dist-upgrade) and everything was functioning normally last time I shut down.

Any ideas on how to get KStars running again?

Here's the Ekos Debug log:

I've downloaded the latest KStars on two Windows machines within the last day and neither is able to download data add-ons. I get message: Could not install [name of catalog]: file not found.

I've not experienced this issue with my Linux/Stellarmate OS version of KStars. Only these new Windows installs.

Is there a fix for this? Or is the data server it's connecting to down?
