我正在尝试使用 openssh 内置 sftp 设置 sftp 服务器。
Subsystem sftp /usr/lib/openssh/sftp-server
并且我按照以下步骤创建了用户（或多或少（使用 ansible），我确实使用 /sbin/nologin 作为 shell，并使用 /dev/null 作为 skel） https://sftpcloud.io/learn/sftp/how-to-setup-sftp-server-on-ubuntu-22-04
但当我尝试连接时
sftp myuser@myip
我收到提示并输入密码，但失败了
client_loop: send disconnect: Broken pipe
Connection closed.
Connection closed
问题是，现在用户的主目录中充满了垃圾。
$ ls -a
snap/ .cache .local
我在系统日志中看到很多事情发生，这些事情似乎与以普通用户身份登录有关（我猜）。以下是一些内容

所以我猜登录会触发“其他操作”，如何禁用正在发生的额外操作，只保留 sftp 呢？我确实有其他“普通”用户登录到我尝试设置为 sftp 服务器的服务器，所以我必须以特殊方式处理这些 sftp 用户。但是该怎么做呢？
我使用 Ubuntu 24.04。我的 sshd_config 显示：
UsePAM yes
