Check to see if SeaHorse is broken

kimconnect@nuc:# seahorse
Gtk-Message: 08:52:44.606: Failed to load module "canberra-gtk-module"
Gtk-Message: 08:52:44.608: Failed to load module "canberra-gtk-module"

Resolve dependency

sudo apt install libcanberra-gtk-module

Run an instance in a disjointed session

nohup seahorse </dev/null >/dev/null 2>&1 &

Explain:

nohup :no hangup
seahorse :some program
</dev/null :direct file descriptors (fd0,fd1,fd2) to the left
>/dev/null 2>&1 :Send standard output to /dev/null and then send standard errors to wherever standard output is going (which is also /dev/null). In short, throw away whatever this command writes to either file descriptor.
& :trigger Ctrl+C equivalent

Kill all sessions with its name to release memory
