Hi all, I have been running extremely well since taking the advice and receiving the support of many on this list. I am grateful those members everyday for its stability. Ed Chan has been an amazing support in creating some backup solutions which have automated the process of achieving efficient data redundancy. I have a Ubuntu 18.04.5 LTS distro with a RAID 1 pair under btrfs.And now I am considering upgrading to another LTS release. Will the commands relating to the RAID survive the upgrade, will the script work from Ed survive the upgrade? In my work as a photographer I find myself in need of GMIC in GIMP, but the latest iteration of GMIC is what I need to recover some work I recently shot. And the latest version of GMIC needs Ubuntu 20.10. Many thanks Andrew Greig
