I tried upgrading PA2050 to from 4.01 to 4.04.
But when I choose upload en the image file the PA starts uploading/checking the image and after a time I receive the error: Invalid Image.
Tried creating a new web server certificate and downloaded the image again but the outcome was still the error.
Then I decided to try upgrading to 4.03 and that succeeded.
Again tried upgrading to 4.04 but without succes.
BTW: I'am staging the appliances so I can't register them at the moment to try automatic installation.
We got same problem, our device is PA-2020.
3.1.10 > 4.0.1 manual software upgrade OK
3.1.10 > 4.0.3 manual software upgrade OK
3.1.10 > 4.0.4 manual software upload failed with error "invalid image"
3.1.10 > 4.0.4 download image directly to the device by clicking the "Download" in Device tab, Software. OK
md5 checked for PanOS_2000-4.0.4.
Switch and redownload for image from another PC, failed with same error. I am sure 4.0.1 image is downloaded to the device before uploading the 4.0.4 image.
License downloaded, contents updated to 263-110 and AV updated to 5559-735 .
