I just tried unsuccessfully updating a customer from 8.1.15 to 8.1.22.
The 8.1.22 image was downloaded on 16/11/22 and I have used it to perform other upgrades successfully.
The customer has a virtual environment hosting a Windows server 2019 instance with only ignition installed. I connected as the system administrator through a console.
First run of the installer, detects that ignition is installed and finds the gateway name (green tick),
I get the usual prompt about taking a backup and press continue.
Installer then says cant detect running gateway do yo want to continue.
If I select yes it gives another error about pre-requisites (assuming that is that it cant stop the gateway it claims to not be able to find)
I hit continue again and it extracts everything before bombing out completely and rolling back.
If I run the installer a second time it detects the install but cant see the gateway name.
I have rolled back the virtual to the snapshot I took prior to the upgrade so no harm done, but interested to know if this is a known issue.
