手动增加网关后,又重新sudo apt-get upgrade, 提示/etc/resolvconf/resolv.conf.d更新时,选Y后,不用手动修改网关也可以连接外网了。
一切默认更新后,18.04LTS的图标问题也修复了。
得到的配置如下
$ cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual nameservers.
nameserver 127.0.0.53
search v01.net
options edns0
可以ping通内网,同时可以ping通8.8.8.8,114.114.114.114, 但是ping外网失败,以下是手动增加网关的一个解决方法,如果还不行就需要查看其它方法了。
10.219.91.1要填你的网关
1. cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
2. route或netstat -rn,获取网关10.219.91.1
$ route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default 10.219.91.1 0.0.0.0 UG 0 0 0 ens33
10.219.91.0 * 255.255.255.0 U 0 0 0 ens33
link-local * 255.255.0.0 U 1000 0 0 ens33
3. 修改/etc/resolvconf/resolv.conf.d/head, 增加如下3行
nameserver 10.219.91.1
nameserver 114.114.114.114
nameserver 8.8.8.8
4. 执行/etc/init.d/networking restart
5. 查看/etc/resolv.conf
$ cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 10.219.91.1
nameserver 114.114.114.114
nameserver 8.8.8.8
6. ping Bing,显示成功
$ ping cn.bing.com
