NetworkManager doubled interfaces

Hey guys,

I just switched to NetworkManager and man, it fixed so many problems. However, now it shows that I have interfaces enp2s0 and 'system enp2s0'. Is that normal? I also have another interface enp4s0 that is doubled. The system ones are marked as never used.

And then, if you see the picture I have too many fake connections. Should they be deleted?

Code: Select all
[root@agronpc ~]# ifconfig -a
enp2s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.1.50  netmask 255.255.255.0  broadcast 192.168.1.255
        inet6 fe80::5246:5dff:fe6a:fb56  prefixlen 64  scopeid 0x20<link>
        ether 90:96:9d:9a:9b:96  txqueuelen 1000  (Ethernet)

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>

        RX packets 39268  bytes 14477177 (13.8 MiB)

Please show the outputs of the following commands, all as normal user:

Code: Select all
LC_ALL=C nmcli -f all c
cat /etc/NetworkManager/NetworkManager.conf
find /etc/NetworkManager/system-connections/ -ls
ls -al /etc/sysconfig/network-scripts/ifcfg-*
cat /etc/sysconfig/network-scripts/ifcfg-*


And your assumption is correct, you should not have those duplicate connections.
