这发生在我上次系统更新之后......重新启动和/或另一个系统更新后相同......有什么想法吗?
Ubuntu 20.04
作为临时解决方法:删除 /var/crash/ 下的所有文件 这不是一个长期甚至中期的解决方案,但总比什么都不要开始好。
旧的过时解决方案见下文更新以获得更好的方法
只需关闭失控服务
apport
然后在重新启动后 systemd cpu 使用率是正常的
即使在再次重新启动后也使用 100% cpu 所以我发出
现在一切都很好
更新
编辑文件
/usr/lib/systemd/system/apport-autoreport.path
保存然后发出
有关详细信息,请参阅 https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1891657
几个月后,这个问题得到解决,下面是健康正常盒子的内容(Ubuntu 20.04 截至 20210812)
