Firefox 和 chrome 无法启动，并出现错误“总线错误（核心转储）”。因此，我运行 apt-get update 并收到错误。我认为原因是 org.freedesktop.systemd1，但我无法进一步解决。我尝试了目前能找到的所有方法，但没有任何变化。
sudo apt-get update
Failed to start apt-news.service: Failed to activate service 'org.freedesktop.systemd1': timed out (service_start_timeout=25000ms)
See system logs and 'systemctl status apt-news.service' for details.
Failed to start esm-cache.service: Failed to activate service 'org.freedesktop.systemd1': timed out (service_start_timeout=25000ms)
