公司开发人员电脑都安装的是Ubuntu 10.04,现在越来越不好用,而且,很多同事发现编译最新的Firefox OS都有问题,所以,我尝试升级并把碰到的问题记录下来。

升级

修改源

:::bash

$ cat /etc/apt/sources.list
deb http://172.26.32.18/ubuntu/ lucid main restricted universe multiverse
deb http://172.26.32.18/ubuntu/ lucid-security main restricted universe multiverse
deb http://172.26.32.18/ubuntu/ lucid-updates main restricted universe multiverse
deb http://172.26.32.18/ubuntu/ lucid-proposed main restricted universe multiverse
deb http://172.26.32.18/ubuntu/ lucid-backports main restricted universe multiverse

# aliyun
deb http://mirrors.aliyun.com/ubuntu/ lucid main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ lucid-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ lucid-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ lucid-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ lucid-backports main restricted universe multiverse

开始升级

:::bash
$ sudo do-release-upgrade

nis无法启动,导致升级过程中配置nis包失败

:::bash
$ grep redhat /etc/hosts
172.26.32.12    cd-redhat-001.TCTCD

$ tail -1 /etc/yp.conf 
ypserver cd-redhat-001.TCTCD

$ cat /etc/defaultdomain 
TCTCD

$ grep NIS /etc/default/nis | grep -Ev '#'
NISSERVER=false
NISCLIENT=true
NISMASTER=

$ cat /etc/auto.master
/home /etc/auto.home

$ cat /etc/auto.home 
xcsu cd-redhat-001.TCTCD:/home/xcsu

$ /usr/lib/yp/ypinit -s cd-redhat-001.TCTCD

$ sudo service portmap restart
$ sudo service nis restart

启动后登录时发现只能用administrator和guest登录

:::bash
$ cat /etc/lightdm/lightdm.conf 
[SeatDefaults]
user-session=ubuntu
greeter-session=unity-greeter
allow-guest=false
greeter-show-manual-login=true

重启电脑,就可以用其它用户登录了

:::bash
$ sudo reboot
