Ubuntu20.04 TLS 开机卡在“A start job is running for wait for network to be Configured”解决
问题:
安装ubuntu20.04 TLS系统后,开机卡在“A start job is running for wait for network to be Configured”等待连接两分多钟。(启动作业正在运行,等待配置网络)
解决办法:
1、进入该目录下,修改配置文件。
kuaibang@face:~$ cd /etc/systemd/system/network-online.target.wants/
2、在[Service]下添加 TimeoutStartSec=2sec,(设置超时时间为2秒)如下:
kuaibang@face:/etc/systemd/system/network-online.target.wants$ sudo nano systemd-networkd-wait-online.service [Service] Type=oneshot ExecStart=/lib/systemd/systemd-networkd-wait-online RemainAfterExit=yes TimeoutStartSec=2sec
3、重启验证
sudo reboot
附加:
swap相关报错,启动必须等1分30秒。
a start job is running for /dev/disk/by-uuid/xxxxx.(20s / 1 min 30 s )
1、解决1
1.1 查看交换分区挂载情况:
swapon --show
1.2 查看交换分区情况:
sudo blkid
1.3 然后再查看/etc/fstab文件中swap分区的UUID。
sudo cat /etc/fstab
两个UUID不同,正好解释了为什么swap分区会挂载失败。
解决方法是删除/etc/fstab文件中swap分区的UUID,
再用sudo blkid命令得出的swap分区UUID替换。保存文件,重启系统后a start job is running for
dev-disk-by这个错误就消失了。
2、解决2
2.1 修改/etc/fstab文件,注掉swap那一行
yang@ubuntu:/path$ sudo cat /etc/fstab # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> # / was on /dev/sda2 during curtin installation /dev/disk/by-uuid/cxxxx06-xxxxc-4xxxx0-xxxxx80-xxxxxxxaac / ext4 defaults 0 1 #/swap.img none swap sw 0 0
2.2 重启不然加载swap分区,即可解决此报错
sudo reboot
