GNUmail and PureOS

[paul deveson]

Hi,

I have seen sites that recommend for PureOS. I have Librem5.  How do I 
install via terminal?

When I have tried by terminal, I am told "Gnome 3.28 runtimes are no 
longer supported". "Freedesktop 1.6 is no longer supported"

Ask the developer.

Are you them ?

Paul
