我最近更新到了 Ubuntu 17.10,并且我尝试暂停,我有这个/var/log/syslog
:
Nov 3 03:24:29 oscar systemd[1]: Reached target Sleep.

Nov 3 03:24:29 oscar systemd-sleep[9867]: Failed to connect to non-global ctrl_ifname: (nil) error: No such file or directory
Nov 3 03:24:29 oscar systemd-sleep[9877]: /lib/systemd/system-sleep/wpasupplicant failed with error code 255.

Nov 3 03:25:27 oscar rsyslogd: [origin software="rsyslogd" swVersion="8.16.0" x-pid="1014" x-info="http://www.rsyslog.com"] start
经过一番调查,我发现了/lib/systemd/system-sleep/wpasupplicant
这一点:
#!/bin/sh
set -e
if [ "$2" = "suspend" ] || [ "$2" = "hybrid-sleep" ]; then
case "$1" in
pre) /sbin/wpa_cli suspend ;;
post) /sbin/wpa_cli resume ;;
esac
fi
当我这样做时sudo /sbin/wpa_cli suspend
,我有这个:
Failed to connect to non-global ctrl_ifname: (nil) error: No such file or directory
此刻,我不知道该怎么办。
我发现在 gnome 界面中检测有线连接时出现了一些问题,但它可以正常工作ifconfig enp4s0
。我得到了以下结果:
enp4s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

这是我的/etc/network/interfaces
:
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
auto enp4s0
allow-hotplug enp4s0
iface enp4s0 inet dhcp
以下是有关我的系统的一些信息:
Linux oscar 4.13.0-16-lowlatency #19-Ubuntu SMP PREEMPT Wed Oct 11 19:51:52 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
我的网卡:
04:00.0 Ethernet controller: Qualcomm Atheros AR8151 v2.0 Gigabit Ethernet (rev c0)
答案1
我找到了解决方案。我在末尾添加了这一行/etc/network/interfaces
:
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
我补充/etc/wpa_supplicant/wpa_supplicant.conf
说:
ctrl_interface=/var/run/wpa_supplicant
ap_scan=0
fast_reauth=0
我仍然无法暂停,但这与这个特定问题无关。
