Error: execUpgradeSoftware : RETR failed...

While doing a IPS Sensor Software update I got the error Error: execUpgradeSoftware : RETR failed...This error only happened during the instructions of upgrading via FTP.

session 1
config t
upgrade ftp://cisco@x.x.x.x/upgrade.pkg

The quick fix for me was to use the GUI update dialog. If you go to update sensor from sensor management under the IPS section or IDM.


After looking into more on the FTP there was a home directory issue with this account. Might be different depending on the FTP with that error. This FTP was running Core FTP.
