Sophos UTM 9.5 USB Install

Recently I was testing out Sophos UTM product and ran into a small issue that was not documented. I could not successfully install the ISO image onto my test hardware via USB thumb drive. After trying multiple downloads, multiple usb sticks and burning the image from different computers I kept getting the same error when trying to install

install.tar wasn’t found on the installation media

I found a great write up over at detailing the workaround.

In short, the installation needs to be told where to look for the install.tar file.

At the blue Introduction Screen press Alt + F2 to switch you to a console screen.

Mount your USB drive with the following command:

mount /dev/sdb1 /install

Press Alt + F1 to switch back to the installer to continue the installation.

Here is the link to the full how to.
