Ubuntu apt get install 软件时出现 E: You don‘t have enough free space in /var/cache/apt/archives/. 解决方案

出现该问题是/var下空间不足，
可尝试apt install clean
清除/var/log内容等方法，
如果还是不行，做个文件路径软连接映射即可
例如：

mkdir -p /home/root/var_archives/partial
sudo rm -rf /var/cache/apt/archives
sudo ln -s "/home/root/var_archives" /var/cache/apt/archives

完成/var/cache/apt/archives映射至/home/root/var_archives，空间充足即可完成安装任务了
