Thank you for taking the time to report this bug and helping to make Ubuntu better.
Bug reporting is about finding & fixing problems thus preventing future users from hitting the same bug. I suspect a Support site would be more appropriate, eg. https://answers.launchpad.net/ubuntu. You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://discourse.ubuntu.com/t/welcome-to-support-and-help/49951, or for more support options please look at https://discourse.ubuntu.com/t/community-support/709 I've marked this bug report as incomplete; it can be changed to a question, but you've filed it against the Ubuntu-Release-Upgrader package which would be used to change a 24.04 system to 25.10 or 26.04; but there is no evidence you've attempted to release-upgrade your system (ie. initiate the tool to move/upgrade your installed system to a newer release). Sweet Home 3D Design Software sounds like a 3rd party app; which isn't handled by the Ubuntu Release Upgrader process anyway (it only performs upgrades on Ubuntu repository packages). Java isn't used; it's just a system package that gets upgraded with the rest of your installed Ubuntu packages. To file bugs against a 3rd party package, you need to use the bug tracker of the software involved (ie. Sweet Home 3D Design Software). That can usually be found where the software is installed from (No results for a package named sw3d in Ubuntu repositories) ** Changed in: ubuntu-release-upgrader (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2139244 Title: Null Pointer Exception in Sweet Home 3D Design Software with KDE and Java To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/2139244/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
