Please add that vital bit of information somewhere appropriate. I would not be surprised if people are still running e.g. 17.10 on some of their Armada 8040 boards. My Macchiatobin which is acting as a server currently has 17.10, although I plan to upgrade it to 18.12 in about three to six months time, once I've well and truely proven that my ext4 problems are resolved. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
