The key thing was to realise that
wasn’t an installer but the program itself so needed to be renamed and moved to /usr/local/bin (as well as the chmod which I’d already done). I do still seem to need the
but I do now seem to have a backup initialising. Fingers crossed. I will stick with the CLI for now but will look out for the next iteration of the web-UI for linux and use that when it comes. Thanks for the help.
If I didn’t stupidly miss something obvious about the renaming then I think the web site for duplicacy could do with better documentation, perhaps particularly for linux.
