Thanks Igor,
the image is the latest one - downloaded two days ago.
Did run apt-get update and upgrade again right now.
Though there is no file named armbian-release in /etc, making "source" protesting "no such file or directory".

Following the instructions from the download page for the Lime2-eMMC we tried to apply the commands listed, but it looks that something is garbled here
source is not a command AFAIK and if I use it as an apt-get option the system complaints about missing entries in sources.
What is the correct way?
