Hi Eugenio. I appreciate your patience, but we haven't been able to reproduce the issue so we depend on our logs to draw out any conclusion.
Is there any change you are using a different software or extension to display your thumbnails other than nautilus directly? Something like gnome-shell-extension-desktop-icons-ng? I don't want to specify a term to look for in the logs because I don't want to miss relevant information, so could you check logs since last the boot? If that's not possible, could you check for apparmor logs that contain "userns"? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2047256 Title: Ubuntu 24.04 Some image thumbnails no longer displayed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/2047256/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
