If you’re receiving any of the above error messages when attempting to upgrade your Teradici thin/zero client then you may find this article useful.
Essentially the solution is to download the firmware increments leading up to the target firmware.
In my case, I had a 10ZiG v1200-P on firmware version 4.1.0 and was trying to upgrade to the latest which is 4.8.0 as of this article.
According to the Teradici support page, I have to install 4.7.1 before I can upgrade to 4.8.0 however I still experienced the errors above so the advice was incorrect for my particular case.
For me to get to 4.8.0, I had to go to 4.2.0 first, 4.5.0 then 4.8.0.
You can find download links for the Tera1 and Tera2 firmware releases on the Teradici support site.
