[GUI Plugin] calibre Auto-Updater

[Terisa de morgan]

My system is Windows 11. I've tested version 1.2.3 and, although the installer is downloaded and calibre ends, nothing else happens, there is no installation and calibre still is stopped.

I've prepared v1.2.4 with two specific fixes for KDE:
Process Detachment: Added a 'setpgrp' flag so the terminal becomes independent of calibre.
Konsole Persistence: Added the --noclose flag which is sometimes required in newer KDE versions to keep the window visible.
If this still doesn't show the terminal, could you please try running calibre from a terminal yourself, try to update, and copy here any error message that appears in the background? That would be incredibly helpful!

Uninstalled the old, and installed the 1.2.4 plugin. This time I get a second error window after clicking "yes" in the updater plugin's dialogue window, which states:

calibre, version 9.5.0
ERROR: Error: No compatible terminal found.

Running Calibre from the terminal shows only the following output. No further output prints to terminal when I try the updater plugin.

Tested v1.2.4 on MacOS 26.3.1. Calibre auto-quit after completing the download, and the disk image auto-mounted. Thanks, looks perfect to me!
