我已经遇到这种情况有一段时间了 - 不太清楚是什么原因造成的。
有一两个进程（这里/usr/sbin/aptd）的 CPU 使用率总是飙升至 98-100％，我不确定如何解决这个问题。
有人介意澄清一下问题是什么吗？卸载 Python 2.7（和依赖项，即 Python 3 等）是否有帮助？
谢谢。
编辑：sudo apt-get update出现以下错误：
david@david-Blade:~$ sudo apt-get upgrade
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

更新 1：
尝试运行sudo killall -9 apt-get并sudo kill -9 _pid_按照说明进行操作这里但似乎我无法做到这一点？因此，dpkg 被另一个进程阻止，我无法运行sudo dpkg-reconfigure -phigh -a或sudo dpkg --configure -a。
david@david-Blade:~$ sudo killall -9 apt-get
apt-get: no process found
david@david-Blade:~$ sudo kill -9 _pid_
kill: failed to parse argument: '_pid_'
更新 2：
运行“sudo dkpg --configure -a”并禁用我的 UEFI 启动器。运行后sudo apt-get update出现以下错误日志：
