以 root 身份登录并通过运行将其改回以前的状态usermod -d /home/florencia florencia。

I don't know what you were trying to do exactly, but you should generally not change your home directory like that.

Answer 2

PLEASE READ EVERYTHING BEFORE MAKING CHANGES!

here is how you want to move a "/home" directory to another drive or location.

1. Logout. You have to be in the TTY only.
2. Open TTY by pressing CTRL+ALT+F1
3. Login using your name and password

now here is where we start doing things.

cd /
sudo mkdir mnt/
sudo mount /dev/sdXX /mnt

note: replace /dev/sdXX with the specific partition or folder destination. example: /dev/sdc1 or /home/backup

now we are going to copy the contents of things.

sudo rsync -aux /home /mnt

unmount the old partition or location

sudo umount /home

delete the old /home

rm -rf /home

get device UUID for fstab

sudo blkid

open fstab and edit

sudo nano /etc/fstab
UUID=copieduuidnumber    /home    ext4    defaults    0   2

note: if you are using a different filesystem then change ext4 to whatever you are using. example: ext3 or ntfs

reboot and see if things are good

sudo reboot

Answer 3

If everything is done correctly and you loop on login page without accessing you might just need to copy your .bashrc to your new home dir
