The system cannot find the path specified when executing jruby

If you get "The system cannot find the path specified" when trying to run jruby in Windows, you need to add JRUBY_HOME and JAVA_HOME to your environment variables. JRUBY_HOME and JAVA_HOME both need to point to the root folder of jruby and Java JDK, e.g.: C:\jruby-1.1.6\ and C:\Program Files\Java\jdk1.6.0_11. You need to also add %JAVA_HOME%\bin and %JRUBY_HOME%\bin to your PATH variable. You can manage your environment variables by doing the following under Windows XP:
  1. Right click on My Computer
  2. Click Properties
  3. Click the Advance tab
  4. Click on Environment Variables

Power Automate: SFTP action "Test connection failed"

When I added an SFTP create file action to my Power Automate flow ( https://flow.microsoft.com ) , I got the following error in the action step, within the designer: "Test connection failed" To troubleshoot the Power Automate connection, I had to: go the Power Automate portal then "Data"->"Connections"  the sftp connection was there, I clicked on the ellipsis, and entered the connection info It turns out, that screen provides more details about the connection error. In my case, it was complaining that "SSH host key finger-print xxx format is not supported. It must be in 'MD5' format". I had provided the sha fingerprint that WinScp shows. Instead, I needed to use the MD5 version of the fingerprint. To get that, I had to run in command line (I was in a folder that had openssh in it): ssh -o FingerprintHash=md5 mysftpsite.com To get the fingerprint in MD5 format. I took the string (without the "MD5:" part of the string) and put
