我连接到服务器，但无法my_username在/gel/usr.有解决方法来解决这个问题吗？我可以在服务器中以某些方式修改 $PATH 来解决这个问题吗？

答案1

如错误行所示，该位置没有主目录

Could not chdir to home directory /gel/usr/my_username: No such file or directory

/home/例如，通常主目录位于/home/username.

您可以/etc/passwd直接编辑文件并输入正确的预先存在的路径，也可以使用命令usermod更改主目录，如下所示：

usermod -d /home/username username

您将需要更改用户名的实例以符合您的情况。
