MySql Workbench無法打開SSH隧道

Question

上周我一直在成功使用MySql Workbench，但是今天早晨，它系統地無法打開SSH隧道。

我檢查了日志，發現以下內容：

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

但是，當我嘗試從終端連接時，SSH連接可以正常工作。 任何想法如何解決這個問題？

發現：

似乎版本6.3.9可能存在錯誤。 我使用以下命令重新安裝了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

我昨天有同樣的問題。 我的解決方案是刪除Workbench及其依賴項，然后重新安裝。 我使用Ubuntu 16.04和Workbench 6.3.6。
