[Qucs-devel] Snap errors

[Chris <chr...@ym...>]

Qucs deb won't run on Ubuntu 20.04 because Qt4 is not available on it. 
Instead I have installed the Snap - which should contain all its 
dependencies. However when run to produce a sim file it produces loads 
of errors:

/Fontconfig warning: "/etc/fonts/conf.d/10-hinting-slight.conf", line 4: 
unknown element "its:rules"//
//.../

/Fontconfig error: "/etc/fonts/conf.d/90-synthetic.conf", line 6: 
invalid attribute 'version'//
//(process:21199): Gtk-WARNING **: Locale not supported by C library.//
//    Using the fallback 'C' locale.//
//Gtk-Message: Failed to load module "gail"//
//Gtk-Message: Failed to load module "atk-bridge"//
//Gtk-Message: Failed to load module "canberra-gtk-module"//
//Warning: Qt: Session management error: None of the authentication 
protocols specified are supported//
//D/

Complete output attached.
