Hi,

--------------------------------------------------------------------------------
1) I am troubled with following problem :
--------------------------------------------------------------------------------
Wait for all "auto" /etc/network/interfaces to be up for network-online.target failed .

[Failed] Wait for all "auto" /etc/network/interfaces to be up for network-online.target.


--------------------------------------------------------------------------------
2) O/P of systemctl list-dependencies network-online.target
--------------------------------------------------------------------------------

# systemctl list-dependencies network-online.target

● └─NetworkManager-wait-online.service


--------------------------------------------------------------------------------
3) O/P of systemctl --all |grep ifup
--------------------------------------------------------------------------------


# systemctl --all |grep ifup

--------------------------------------------------------------------------------
4) cat /etc/network/interfaces
--------------------------------------------------------------------------------

# cat /etc/network/interfaces

--------------------------------------------------------------------------------
5) ifconfig
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
6) Question :
--------------------------------------------------------------------------------

1) Why auto /etc/network/interfaces to be up for network-online.target failed ?
2) whether pppoeconf is causing problem ?

Thanks

So eth0 is up, but the other two aren't. I suppose the third one is not supposed to be up anyway, so that the ppp interface should be the culprit.

Try ifup dsl-provider. There should be an error message, hopefully providing some clarity. And/or check what's in /var/log/syslog.

By the way, ifconfig is deprecated. Use the ip address command instead.

Hi,

Thanks for the reply .

Kindly give me suggestion get rid of this error messages .

Thanks

I don't know how pppoe is configured, but I guess when it was configured enp7s0 existed, but not anymore. Perhaps pppoeconf needs to be run again.

Remove the entry from interfaces would be the easy way, but you would have to do something to get conncted to DSL.

Hi,

Thanks for reply.

I have commented dsl-provider in /etc/network/interfaces

# cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.1.21
netmask 255.255.255.0


#auto dsl-provider
#iface dsl-provider inet ppp
#pre-up /bin/ip link set enp7s0 up # line maintained by pppoeconf
#provider dsl-provider

#auto enp7s0
#iface enp7s0 inet manual
#

After that issue got resolved .

# systemctl --all |grep ifup
ifup-wait-all-auto.service loaded active exited Wait for all "auto" /etc/network/interfaces to be up for network-online.target
ifup@eth0.service loaded active exited ifup for eth0
system-ifup.slice loaded active active system-ifup.slice
#


one doubt, in future whether I will able to configure new pppoeconf or not ?

Thanks
MAK

I have to admit, I don't know anything about connecting a computer to DSL via PPP, but I don't think there will be a problem. As long as you configure PPP with the correct interface.

Hi,

Thanks .
