更改軟件源
更改軟件源的原因
因?yàn)閯偘惭b好的Ubuntu在更新軟件的時(shí)候使用的是國外軟件源，下載速度較慢，所以將軟件源更改成國內(nèi)源可以提高下載速度。
更改軟件源步驟
-
找到軟件源文件sources.list的位置
sources.list文件位置 -
先把原來的軟件源文件備份，以免更改發(fā)生錯(cuò)誤的時(shí)候無法恢復(fù)
備份指令
備份以后文件顯示 -
完成備份以后，打開sources.list文件進(jìn)行更改
使用nano編輯sources.list
把地址（綠色部分）全都改成國內(nèi)源终佛，我用的是阿里云的軟件源
修改成阿里云的軟件源 - 你也可以使用其他的國內(nèi)源，主要可以從以下幾種進(jìn)行選擇：

更改完以后雾家，更新軟件源
更新軟件源 - 至此完成軟件源的更改
虛擬機(jī)Ubuntu18.04全屏
- 首先確保已經(jīng)安裝了 VMware Tools铃彰，如果沒有安裝，可在虛擬機(jī)→安裝VMware Tools芯咧，我這里已經(jīng)安裝好了
點(diǎn)虛擬機(jī)里面的安裝 -
安裝open-vm-tools
安裝open-vm-tools - 在安裝的過程中就已經(jīng)能全屏了
