If all you want is a single wireless connection which is activated when
the machine boots you do not need a wpa_supplicant.conf. Everything can
be done in /etc/network/interfaces. It is the simplest, most hassle-free
and most straightforward way to proceed.
First check that network-manager is not managing the interface you are
going to define in /e/n/i. /etc/NetworkManager/NetworkManager.conf needs
to have
[main]
plugins=ifupdown,keyfile
[ifupdown]
managed=false
Also check the wireless interface name with 'ifconfig -a'. Previously
you said it was wlx00c0ca364bd2.
Now, into /etc/network/interfaces put
allow-hotplug wlx00c0ca364bd2
iface wlx00c0ca364bd2 inet dhcp
wpa-ssid whatever
wpa-psk whatever
This is all you require in the file.
Reboot or use 'ifup -v wlx00c0ca364bd2'.
