按照本文概述的所有步骤回答，在标题为如何通过 WiFi 而不是 USB 安装 Android 外部存储，我仍然不知道如何在 Ubuntu 20.04 上通过 SSH 无线安装我的 Android 手机。
在手机上安装 SSH/SFTP 服务器 - 终端后，我可以通过 SSH 成功连接到服务器，但无法将其作为文件系统挂载。
当在 Thunar 中输入 URI 时，什么也不会发生，而当将路径添加到顶级目录时，最初文件系统似乎已被挂载，只是在假定的挂载点的文本编辑器中打开了一个名为“sdcard”的空白文件，但实际上什么都没有挂载。ssh://[email protected]:2222/sdcard
echo obalaban | sshfs -o password_stdin -p 2222 [email protected]:/ /mnt/samsung
read: Connection reset by peer
我通过编辑 /etc/fuse.conf 并启用该行修复了此错误user_allow_other。
我使用公钥身份验证并尝试将密钥复制到远程文件系统，但没有成功。普通 ssh 登录可以正常工作。因此我尝试在 sshfs 中进行调试：
sshfs -odebug,sshfs_debug,loglevel=debug -o allow_other,default_permissions -p 2222 [email protected]:~/ /mnt/samsung
