Ubuntu Mate 20.04 软件更新程序失败

在日志转储之前使用其他信息进行编辑：

我最近安装了（新的，而不是升级的）Ubuntu Mate 20.04，它工作得很好（大部分情况下它仍然运行良好），但截至今天，我注意到它没有运行更新。

如果我启动更新程序，它会检查并告诉我许多更新已准备就绪，但只要我单击更新按钮，它就会崩溃。这是 /var/log/syslog 从单击按钮到死亡的内容。

任何人都可以在这里提供调查途径吗？或者更好，当然，修复！？

编辑：我再次尝试，取消选择建议的更新，发现实际更新会成功进行。导致问题的原因是“要删除未使用的内核更新”。我尝试取消选择前三个，但它崩溃了，然后我再次运行它并尝试取消选择最后三个，它仍然崩溃。所以看起来删除过程是问题的原因，也许而不是这些事情中的任何一个？
