If I then test systemctl is-enabled netctl-auto@wlp3s0-Arin-1.service
returns enabled
If I test
ip link
returns (in line 3 which is the relevant bit)
wlp3s0: <BROADCAST, MULTICAST, UP LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000 link/ether: 62:dd:d8.... brd ff:ff:... permaddr 8c:70:5a....
If I try systemctl start netctl-auto@wlp3s0-Arin-1.service
It asks for username, and after I enter the username and password, it hangs for about five minutes and then returns an error message
" A dependency job for netctl-auto@wlp3s0-Arin-1.service has failed. See journalctl -xe for details"
I then do journalctl -xe,
and it returns,
" … (some standard text stating failure )then
The job identifier is 1696 and the job result is dependency.
… more standard text then
Unregistered Authenticaltion Agent for unix-process:2416:100184 (system bus name:1.154 … )"
Nothing seems to work to get back the wifi connection.
What do I need to do to get back to (a) a stable internet connection, and (b) when I reboot, I will get back on the Internet?
This problem started after a recent update (as in yesterday)
I have disabled wpa_supplicant.
I cannot uninstall networkmanager as Arch complains about dependency and it will not let me uninstall it.
We’re not using netctl as the default network manager. Was networkmanager enabled at the time? If you disable netctl and enable NetworkManager do you still have the same problem?
Can you post the command and full output as to what happens when you try uninstalling networkmanager?
Yes networkmanager was enabled.
If i disable netctl running systemctl disable netctl.service and issue systemctl enable networkmanager, it returns error message,
Failed to enable unit: Unit file networkmanager.service does not exist.
Command for uninstall networkmanager
pacman -R networkmanager
Returns error:
Failed to prepare transaction (could not prepare dependencies)
Removing networkmanager breaks dependency networkmanager required by archlabs-netwoekmanager-dmenu and
Removing networkmanager breaks dependency required by networkmanager-applet
nmcli shows
wlp3s0 : connecting to $ssid
Then nmcli device wifi connect ssid password password returns
Connection activation failed wi fi network could not be found
@natemaia, if it helps, I found further that if I issue
systemctl --type=service to test what other services are running, I get to see that every service runs OK, except netctl@wlp3s0\x2dArin\x2d1.service (which is essentially “netctl@wlp3s0-Arin-1.service”, the netctl-auto@wlp3s0.service runs just fine. The wpa_supplicant.service runs fine.
At that point, if I issue sudo dhcpcd wlp3s0,
I get back the internet connection
So, is it that netctl-auto@wlp3s0.service and netctl@wlp3s0-Arin-1.service are conflicting with each other? It should be only netctl-auto@wlp3s0-Arin-1.service really that should run, isn’t it?
I have disabled NetworkManager.service as you advised.
When I rebooted, internet connection (wifi) is now working.
However, during boot, it still could not activate netctl-auto@wlp3s0-Arin-1.service, so when I issued systemctl status netctl-auto@wlp3s0-Arin-1.service
it showed:
Loaded: loaded (/usr/lib/systemd/system/netctl-auto@.service; enabled; vendor preset: disabled)
Active: inactive (dead)
But the connection is working, :-),
what will fix this error or does it not matter?
Thank you @Head_on_a_Stick, I think I have disabled netctl profile wlp3s0-Arin-1 and the machine now reboots and I do get the wifi access. But when I invesigated why netctl was failing, and issued, journalctl --unit netctl@wlp3s0-Arin-1.service, it returned
"Starting networking for netctl profile wlp30/Arin/1
Profile wlps30/Arin/1 does not exist
"
Of course it does not exist!
Why is it searching for this profile or what needs to be done? How can I even disable or remove a profile that does not even exist? How do I find out what profile it starts networking for?
I think your problems may be caused by incorrect use of netctl — you’re not supposed to use systemctl to enable or disable it directly — and there also appears to be some confusion in this thread as to whether netctl or netctl-auto is being used. Please read the ArchWiki page linked above, it explains how to use it properly.
Thanks @subjunkie and @Head_on_a_Stick, you are correct. I was wrongly using netctl. For the time being netctl being disabled, and networkmanager enabled, things seem to be as expected with respect to wifi connection, but I need to read closely the netctl documentation and more widely, the systemd documentation. As I understand, netctl is for enabling/disabling/starting/stopping profiles while systemctl is for enabling/disability/starting/stopping services associated with the profiles. So, if I were to disable networkmanager again, and wanted to switch over to netctl, I’d have to issue something like:
netctl enable <profile> and systemctl enable netctl-auto@<profile>.service
The is already saved as a file in /etc/netctl/ folder
No, netctl and netctl-auto are two different things. For netctl-auto you should enable it for the interface rather than the profile and you shouldn’t have plain netctl enabled at the same time.
