这个错误通常表示你在远程 Ubuntu 系统上输入的用户名或密码不正确,或者你没有使用正确的 SSH 密钥进行认证。
你可以尝试以下解决方法:
1. 确认你输入的用户名和密码是否正确。注意,Linux 系统中用户名和密码是区分大小写的。
2. 如果你使用的是 SSH 密钥进行认证,请检查你的密钥是否正确,并且已经添加到目标主机的 authorized_keys 文件中。
3. 确认远程 Ubuntu 系统的 SSH 服务已经开启,并且允许你的 IP 地址进行连接。
4. 如果你仍然无法连接到远程 Ubuntu 系统,可以尝试重置你的密码或者重新生成 SSH 密钥,然后重新尝试连接。
5. 如果你仍然无法解决问题,可以尝试联系目标主机的维护人员,或者查看系统日志以获取更多信息。

远程copy出现Permission denied, please try again.
"Permission denied, please try again" usually occurs when you don't have the necessary permissions to perform the remote copy operation. Here are a few things you can try to resolve the issue:
1. Check your permissions: Make sure you have the appropriate permissions to access the source and destination locations. If you are not the owner or don't have sufficient privileges, contact the owner or an administrator to grant you the necessary permissions.
2. Use sudo: If you have administrative access to the system, try using the sudo command before the remote copy command. This will elevate your privileges and might allow you to perform the operation successfully.
3. Check file and folder permissions: Ensure that the files or folders you are trying to copy have the correct permissions set. You can use the chmod command to modify the permissions if needed.
4. Check network connectivity: Verify that you have a stable network connection between the source and destination systems. Unstable connections or network issues could cause permission denied errors.
If none of these solutions work, please provide more details about your specific situation, including the exact command you are using and any error messages you receive.

这个问题可能是由于以下原因导致的:
1. 用户名或密码错误。
2. SSH服务未启动。
3. 防火墙阻止了SSH连接。
您可以尝试以下解决方法:
1. 确认您输入的用户名和密码是否正确。
2. 确认Ubuntu上的SSH服务是否已启动。您可以在Ubuntu上运行以下命令来检查SSH服务状态:`sudo service ssh status`。如果SSH服务未运行,则可以使用以下命令启动它:`sudo service ssh start`。
3. 检查Ubuntu上的防火墙设置,确保SSH端口(默认为22)未被阻止。您可以使用以下命令检查防火墙设置:`sudo ufw status`。如果SSH端口被阻止,则可以使用以下命令打开它:`sudo ufw allow ssh`。
