Oh, good! Because I had the same problem with the new SD card (updates would seem to get stuck in terminal, or clicking on folders would do nothing) and I realized that it was really just the GUI that was frozen. If I closed the tab on my browser and opened a new dex.local and logged back in, everything would be updated/open. But then it would freeze again. I was beginning to wonder if it was a hardware issue.
I’ll hold tight until you let me know it’s good to go. (and how to proceed).
