虽然看起来这个问题，那里的答案没有帮助：
$ busctl | grep systemd1
org.freedesktop.systemd1 - - - (activatable) - - -
（硬重启后，此行不存在(activatable)。）
$ systemctl daemon-reexec
$ sudo kill 1
$ busctl | grep systemd1
org.freedesktop.systemd1 - - - (activatable) - - -
$ systemctl --version
systemd 246 (246.6-1ubuntu1.3)

所以我无法重新启动它，并且版本高于 236，这有问题。
我该如何恢复？在当前状态下，我无法注销或关机。我必须硬重置。而且 apt 升级失败。

显然clamav是罪魁祸首。也会戳他们。
