我正在尝试dep ensure在我的 Ubuntu 16.04 上运行该命令，但系统无法找到该命令。当我运行sudo apt install dep或任何其他安装命令时，我总是在运行时收到此错误dep ensure：
No command 'dep' found, did you mean:
Command 'dp' from package 'speech-tools' (universe)
Command 'iep' from package 'emboss' (universe)
Command 'dwp' from package 'binutils' (main)
Command 'dex' from package 'dex' (universe)
Command 'rep' from package 'rep' (universe)
Command 'delp' from package 'fp-utils-3.0.0' (universe)
Command 'xep' from package 'pvm-examples' (universe)
dep: command not found
有人告诉我我需要 Ubuntu 18 才能运行dep，但我想知道如何在我当前的 Ubuntu 上安装它。谢谢。
