@jmburgos thanks for reporting. Please specify what did you do before QGIS began to crash trying to start it: did you update your OS or libraries used by QGIS and/or did you update QGIS and/or did you install or uninstall or update any QGIS plugin? |

Hi Andrea, it is hard to say. I regularly update my computer, so I do not remember exactly what packages where updated in the last days. I can dig into the dnf logg and see what changed, but is there anything in particular I should be looking for? I did tried deleting the profile folder (at |

Perhaps @manisandro may have some clues. |

Same problem, identical error output, Fedora 39 and QGIS 3.34.2 (package 3.34.2-1.fc39 installed via I'm running KDE as a DE; switching between Wayland and X11 had no effect. Using Sway instead of KDE also had no effect; behavior was the same all around. QGIS 3.28.9 LTS installed via Flathub launches and runs on the same system without issue. After uninstalling QGIS 3.34.2 and installing the |

Might be the Ditto for 3.34. Installing python3-qgis breaks it. Removing it allows QGIS to launch. Python support is unfortunately required for me for plugins, so this is a showstopper. |

qgis-3.34.3-2.fc40 is working fine here on rawhide. There is a qgis-3.34.3-2.fc39 here [1], does this build suffer from the same issues? [1] https://koji.fedoraproject.org/koji/buildinfo?buildID=2368369 |

Reproduced the above behavior on a clean install of stock Fedora 39 Workstation in a KVM virtual machine ( Same behaviors as on hardware: QGIS launches without error when python3-qgis is not installed, crashes as The |

Is python-qt5 at python-qt5-5.15.10-2.fc39 or at python-qt5-5.15.9-7.fc39? |
|
Confirmed that Qgis runs if I remove python3-qgis-3.34.2-1.fc39.x86_64. |
Neither, no package named On the stock F39 VM where qgis with python3-qgis is broken, python3-qt5-5.15.9-6.fc39 is installed. On my hardware where qgis with python3-qgis is broken, python3-qt5-5.15.10-2.fc39 is installed: |
|
After updating python3-qt5 on the VM to 5.15.10-2, QGIS launches on it without error. Still no idea why it fails on hardware. |
|
Looking back at #56058 (comment), the list of packages that python3-qgis downgrades includes python3-qt5-base to a different version (5.15.9.6). Not sure why. |
|
Think I have it: Hardware was once a F38 system upgraded to F39. The upgrade apparently couldn't resolve an unrelated qt5 package that was already installed (
To confirm, I checked if So tl;dr, removing Not sure if QGIS 3.3x should require a specific python3-qt5 version here, but at a minimum it seems to be incompatible with 5.15.9-6. |
|
https://bugzilla.rpmfusion.org/show_bug.cgi?id=6851 documents the qt5-qtwebengine-freeworld package issue at rpmfusion that results in an updated F39 system installing an outdated python3-qt5. |
|
I think this issue report can be closed, since the issue is not in QGIS itself. |

Thank you all for your help. After following @oznogon I can run QGIS and life can go back to its productive normality. :) |
|
@oznogon thanks for the detailed write up! I just hit this one myself, and your post saved me a lot of wasted time 🙏 |
