No longer seeing previews, or open viewer

ramjet1953 · 09-09-2025, 11:35 PM

Install is on Endeavour OS (Fork of Arch Linux) using:

Code:

sudo -v && wget -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sudo sh /dev/stdin

For years all has been fine all has been fine.

This morning, Calibre opens but does not display anything in preview pane when editing. it just displays in pane 'Loading preview, please wait....'

When trying to view e-book, it just sits there forever, trying to load book.

I have tried re-installing the program and restoring the database, all to no avail.

Other functions seem to be working OK

I am not running it in sudo mode.

Any ideas?

Regards,
Roger

Works fine on my up-to-date Arch system. Most likely some Wayland specific breakage with Qt WebEngine on your distro. Use QT_QPA_PLATFORM=xcb and you should be fine.

Hi, there!
Thank you for your quick reply. I have sorted it out, but don't really know why I am having problems with the wget install. I deleted the current wget install and firstly reinstalled it with with the flatpak. That worked perfectly. I then removed the flatpak and installed it from the official Endeavour OS repositories. That also worked perfectly, so I'll stick with it. Like I said, I don't know why the wget install fails.

Regards,
Roger

The flatpak and Endeavour OS repo versions work perfectly.
I'll stick with the Endeavour OS repo version for now.

You should never install calibre from any repository. It usually will cause all sorts of problems. Get it from the official calibre site.

Did you not read the original message????
The wget download fails to run properly, not showing any preview, or view of ebook.
What good is the website download for me if it doesn't work?
