Xubuntu 20.04.6升级至22.04时do-release-upgrade执行失败求助

各位好，我在尝试把Xubuntu 20.04.6升级到22.04的过程中卡壳了，想求助大家帮忙分析下问题！

为了能推进升级流程，我先手动卸载了几个相关包：gnome-software、gnome-software-common、gnome-software-plugin-snap和ubuntu-software——这是因为之前遇到了包被滞留的情况，才不得不做这个操作。

之后我借助script(1)工具来运行do-release-upgrade命令，结果在执行到触发器环节，输出完以下内容后就直接失败了：

Reading state information... Done

Error in sys.excepthook:

麻烦各位帮我看看这个报错是哪里出了问题，该怎么解决才能顺利完成升级呢？
