OK peeps, thanks for all the lengthy replies about red text. Short answer that I and probably many others would prefer is "Sorry not working yet, check in 3-4 months or try ... image". Either way, I tried Orange Pi Prime Debian server from http://www.orangepi.org/downloadresources/. Works amazingly well, apart from HDMI resolution, which I really don't care much about. I am leaving X on it, just so I can adjust my router settings if need arises. If it wasn't for that, X would be gone in order to save space. Either way, I am quite happy with the board. Thank you all for all the help.

I assume that red warning sign would mean minor issue, not completely not working. But i guess that is reasonable. I will try some other Debian Linux since it really makes little difference to me. Any suggestions what could be good for this board?

After upgrade ubuntu server stops booting and working on Orange Pi Prime (H5, 2GB, WiFi...). Upgrade goes from image (Armbian_5.32.170706_Orangepiprime_Ubuntu_xenial_dev_4.11.8.img) correctly (sudo su... apt-get update, apt-get upgrade, plus install of mc, apache2, mysql, php, phpMySql ... apt-get autoclean). After it is done, I log in using Putty, and the system is still usable but on the login screen there is a message "Kernel upgraded, please restart" (or similar). once logged in I did "init 6" to restart, and Putty is disconnected, and no more response. that is it. Pressing any buttons on the board, disconnecting and reconnecting network, disconnection and reconnecting power supply produces no results. Only network and power are connected to the board, no keyboard or screen since it is meant to be a small web server. Not even LEDs turn on. It appears completely dead. After I replace the image on the SD card, the Pi starts working again normally. I am using 4GB SD, and initially there is some 50% free space. After upgrade I think it drops down to 40%, but there is still sufficient space. CPU is warm to touch, I would assume some 40-45' C (105-115' F). The rest of the board is cool. I repeated the process 3 times up to now, assuming that it was my error, but with same results all 3 times. I still didn't try checking the card on another Linux PC, since I have access only to "Ubuntu - Live CD". Please help.
