客户端是 Macbook Pro（MacOS 13）。服务器 PC 是 Ubuntu 22.04。当我从服务器 shell 执行 sshls ~/.ssh或时ls ~/.config，出现错误cannot access '/home/username/.ssh': Permission denied (os error 13)。
因此，我扩展了对目录的访问权限，例如~/.sshby doingchmod 777等等。
sudo chmod 777 ~/.ssh
cd ~/.ssh
sudo chmod 777 . /*
但是，如果我ls ~/.ssh像以前一样操作，我会得到类似的输出cannot access '/home/username/.ssh': Permission denied (os error 13)。
我想知道如何解决连接 ssh 时丢失对 dotdirectries 的访问权限的问题。
ls -la
输出是

cannot access '/home/username/.ssh': Permission denied (os error 13)当我ls针对以点开头的目录（例如 ~/.cargo 目录，而不仅仅是 ~/.ssh 目录）时，会出现错误。
