Thanks for the report. This is not a bug, it results from a change in system requirements. Specifically, you need a more recent version of Qt, so likely need to update your OS. Ubuntu 22.04 (and variants) or above should have a suitably recent version by default. See the release notes: https://wiki.documentfoundation.org/ReleaseNotes/24.2#Platform_Compatibility *** This bug has been marked as a duplicate of bug 159494 ***
OK thank's for this response. i will wait for the integration of libreoffice in lubuntu (if possible) or stay on old version. It's complicated to migrate the whole system to 22.04 or 24.04. i have some issues with other softwares (auto-multiple-choice - giac xcas,....)
You might be able to install Qt 5.15, but I can't guarantee it will work or not cause other issues.
