我正在尝试在 Ubuntu 18.04 中使用虚拟盒客户机,但现在无法成功。
peter@LAPTOP-UMBBINAR:~$: sudo apt-get install virtualbox-guest-additions-iso
peter@LAPTOP-UMBBINAR:~$ Reading package lists... Done
Reading: command not found
peter@LAPTOP-UMBBINAR:~$ Building dependency tree
Building: command not found
peter@LAPTOP-UMBBINAR:~$ E: Unable to locate package virtualbox-guest-additions-iso
知道如何运行该命令吗?
