Rob I'm working through the errors I'm hitting and finding some packages which appear to have changed names etc. For instance libwxgtk3.0-dev no longer has a candidate but I found a note for Ubunto that it was renamed to libwxgtk3.0-gtk3-dev in Ubuntu 20.04 (askubuntu.com/questions/1241217/package-...date-on-ubuntu-20-04) and trying that name in the script it looks to be working.
Are you still maintaining the scripts and interested in the details once I've either finished or got as far as I can? If so how what is the best way to pass that on? I don't know that I'll stick with the T95 max long term, the ODroid N2+ looks pretty interesting but am finding the build process interesting and hopefully educational.
