我正在升级 Ubuntu 7.04 服务器上的 openssh-server 包apt-get upgrade，以修复 debian PRNG 安全漏洞。我通过 SSH 连接（Windows 上的 putty）执行此操作，我认为这没问题，但是...
升级似乎挂在下面了，就像它想让我在“窗口”中单击“确定”，但我当然不能，因为我只是在一个外壳中。
设置 openssh-server (4.3p2-8ubuntu1.5) ... 包配置

â Vulnerable host keys will be regenerated â
â â®
â Some of the OpenSSH server host keys on this system were generated with â
â a version of OpenSSL that had a broken random number generator. As a â
â result, these host keys are from a well-known set, are subject to â
â brute-force attacks, and must be regenerated. â
â â
â Users of this system should be informed of this change, as they will be â
â prompted about the host key change the next time they log in. Use â
â 'ssh-keygen -l -f HOST_KEY_FILE' after the upgrade has changed to print â
â the fingerprints of the new host keys. â
â â
â The affected host keys are: â
â â
â
â <Ok>
â â

我注意到我无法再将任何新的 ssh 会话连接到服务器，但我打开的现有会话仍然可以工作。
有什么想法我该如何进行吗？

确保 Putty 窗口处于焦点状态，然后尝试按“Enter”。如果不起作用，请按“Tab”直到“< Ok >”突出显示，然后再次尝试“Enter”。
