I am facing a problem where although I am connected to the network I cannot find any connections on my NM applet. I added a VPN configuration also there and whenever I try to log into it i get a prompt that says
Could not find source connection.
My /etc/network/interfaces contents are:
# interfaces(5) file used by ifup(8) and ifdown(8)
# Include files from /etc/network/interfaces.d:
#source-directory /etc/network/interfaces.d
#auto eno1
#iface eno1 inet dhcp
#gateway my_gateway_address
iface eno1 inet static
address my_ip_address
gateway my_gateway_addres
I have tried re-installing all the network manager packages and I had no luck with making my connections appear...
Here is the output of the nmcli -p -f general device show eno1:
