在第一次登录之后, 我发现每次输入密码麻烦就加了公钥到机器上, 可以自行添加这个目录以及文件

corvo@HomeFN:~$ ls ~/.ssh/authorized_keys /home/corvo/.ssh/authorized_keys

Welcome to fdisk (util-linux 2.38.1). Changes will remain in memory only, until you decide to write them. Be careful before using the write command.
GPT PMBR size mismatch (12582911 != 16777215) will be corrected by write. The backup GPT table is not on the end of the device. This problem will be corrected by write. This disk is currently in use - repartitioning is probably a bad idea. It's recommended to umount all file systems, and swapoff all swap partitions on this disk.
