一、问题
在Docker中 vim无法直接使用
二、解决
首先更换Docker 镜像源 /etc/apt/sources.list
cat > /etc/apt/sources.list << EOF deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse EOF
更新apt-get update
如果更新时出现如下错误：
You might want to run 'apt --fix-broken install' to correct these. The following packages have unmet dependencies: apt-transport-https : Depends: libcurl3-gnutls (>= 7.16.2) but it is not going to be installed vim : Depends: vim-common (= 2:8.1.2269-1ubuntu5.29) but it is not going to be installed Depends: vim-runtime (= 2:8.1.2269-1ubuntu5.29) but it is not going to be installed Depends: libc6 (>= 2.29) but 2.24-11+deb9u3 is to be installed Depends: libcanberra0 (>= 0.2) but it is not going to be installed Depends: libgpm2 (>= 1.20.7) but it is not going to be installed Depends: libpython3.8 (>= 3.8.2) but it is not going to be installed Depends: libtinfo6 (>= 6) but it is not going to be installed E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
执行修复命令：
apt --fix-broken install
检查并安装依赖包
apt-get install libcurl3-gnutls
如果遇到冲突文件，使用
dpkg -i --force-overwrite 强制覆盖冲突文件
最后再此更新
apt update
重新安装vim
apt-get install vim
操作步骤命令：
