# 升级安装
sudo yum update -y vim*

sudo apt-get install software-properties-common python-software-properties

# 添加源
sudo add-apt-repository ppa:nmi/vim-snapshots

# 更新及安装
sudo apt-get update
sudo apt-get install vim

# 如果需要删除或者说叫降级的话
sudo apt-get install ppa-purge
sudo ppa-purge ppa:nmi/vim-snapshots

cd  /etc/apt/sources.list.d/ # then delete whatever you want

# 下面这条似乎没生效
sudo add-apt-repository -r ppa:user/ppa-name
