Calibre won't start after update to 7.17

nerdyreader · Yesterday, 01:06 PM

Last night, I updated Calibre to version 7.17 and after that, it's refusing to open.

I am running Fedora 39 (Linux) and all my packages are up to date (I just updated them as well).

When I try to start Calibre from the terminal, I get this message:

Code:

$ calibre
qt.gui.imageio: libpng warning: iCCP: known incorrect sRGB profile

It also briefly flashes the Calibre opening graphic in the GUI. After that, if I go to the hot corner, I can see the Calibre icon sort of floating there but it never opens.

I also tried

Code:

$ calibre --ignore-plugins

This gets rid of the libpng warning but Calibre still doesn't start.

It's been a wonderful piece of software before this though!

Thanks for any help. Happy to provide any additional data if you can specify.

Are you using the official calibre binaries or the fedora package of calibre?

At a wild eyed guess, I would say he is running the official calibre binaries. My Fedora 39 VM shows 7.13 as the latest calibre version in the repository. Perhaps the QT 6.7.2 and video driver battle continues on their computer?

Edit: I should mention that this was a first install of calibre on the Fedora 39 VM and I needed to install libdeflate ( libdeflate-1.21-2.fc39.x86_64) to allow calibre to finish starting up.

Edit 2: Corrected typo in version number.

Yes currently the Wayland ecosystem is totally broken again for people with some compositors and nvidia cards because of something called explicit sync. @nerdyreader: What compositor are you using and what video card?

On my Fedora 39 VM, running inxi -Gxx | grep compositor gives me:

compositor: gnome-shell v: 45.9 driver: dri: vmwgfx gpu: vmwgfx
