MySql Workbench 无法打开 SSH 隧道

Question

上周我一直在成功使用 MySql Workbench，但是今天早上，它系统性地无法打开 SSH 隧道。

我检查了日志，发现如下：

16:46:47 [INF][     SSH tunnel]: Existing SSH tunnel not found, opening new one
16:46:54 [INF][     SSH tunnel]: Opening SSH tunnel to 192.168.200.254
16:46:55 [ERR][sshtunnel.py:notify_exception_error:235]: Traceback (most recent call last):

16:47:00 [INF][     SSH tunnel]: Existing SSH tunnel not found, opening new one

然而，当我尝试从终端连接时，SSH 连接工作正常。知道如何解决这个问题吗？

调查结果：

似乎 6.3.9 版本可能存在错误。我使用以下内容重新安装了 MySql Workbench（我在 Ubuntu 上）：

# The following will remove mysql too
sudo apt-get remove --purge mysql*

sudo apt-get autoremove
sudo apt-get autoclean

sudo apt-get update

# Then reboot your PC

# Re-install MySql Workbench from the Ubuntu software application

我昨天也遇到了同样的问题。我的解决方案是删除 Workbench 及其依赖项并重新安装。我使用 Ubuntu 16.04 和 Workbench 6.3.6。
