Hi, thank you for your answer. Question from my side is, what to do to get working again (before update/upgrade) it was working. For me (as quite newby) it’s not clear.
Or, is there any way to install “old” dietpi version and disable dietpi upgrade which is disaster for me?
If you need some tests, please write me.
Thanks
edit: is a solution use a user overlay described here ?
