如何在Ubuntu18.04上安装引导图？

Question

引导图不再可用了吗？是否有等效的图形工具？

sudo apt install bootchart  
E: Package 'bootchart' has no installation candidate
 sudo snap install bootchart
error: snap "bootchart" not found

我的分析链似乎毫无帮助：

systemd-analyze critical-chain 
The time after the unit is active or started is printed after the "@" character.
The time the unit takes to start is printed after the "+" character.



graphical.target @17.301s
└─multi-user.target @17.301s
  └─snap-node-2082.mount @56.794s +60ms
    └─local-fs-pre.target @1.903s
      └─keyboard-setup.service @226ms +1.367s
        └─systemd-journald.socket @224ms

将systemd的包名从bootchart更改为systemd-bootchart

尝试在18.04及更高版本中安装systemd-bootchart。
