Hi Richard,

Thanks for getting back to me so quickly on this question and I was afraid
that this was the case.

I will probably definitely still use libguestfs as it does some things that
I really need as well if I can get it to compile without errors on my
Ubuntu 20.04 system.  Currently seems to be having some problems during the
"make" process when it gets partially through the Erlang section but I
am
investigating now.

Is there, by chance, a mailing list or forum available as I would like to
report the errors and get some input on possible fixes?

Best Regards,

Lonnie
