Installing snap on Kubuntu

doc
1

If you’re running Kubuntu 16.04 LTS (Xenial Xerus) or later, including Kubuntu 18.04 LTS (Bionic Beaver) and Kubuntu 18.10 (Cosmic Cuttlefish), you don’t need to do anything. Snap is already installed and ready to go.

If you need to know which version of Kubuntu you’re running, select About System from KInfoCentre. Alternatively, from the command line, type lsb_release -a.

Versions of Kubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf) don’t include snap by default, but snap can be installed from the command line as follows:

$ sudo apt update
$ sudo apt install snapd

Hi! I cant run snap-store on Kubuntu 20.04 Focal Fossa.

drmohm@Jack:~$ snap-store
14:50:50:0695 Gtk Locale not supported by C library.
Using the fallback ‘C’ locale.
14:50:51:0992 GdkPixbuf Cannot open pixbuf loader module file ‘/home/drmohm/snap/snap-store/common/.cache/gdk-pixbuf-loaders.cache’: No such file or directory
This likely means that your installation is broken.
Try running the command
gdk-pixbuf-query-loaders > /home/drmohm/snap/snap-store/common/.cache/gdk-pixbuf-loaders.cache
to make things work again for the time being.
14:50:52:0057 Gtk Failed to load module “appmenu-gtk-module”
14:50:52:0063 GLib-GIO No GSettings schemas are installed on the system
Trace/breakpoint trap (core dumped)

What is the reason?
