删除多余的软件包:
apt-get remove thunderbird unity-webapps-common totem rhythmbox empathy brasero simple-scan gnome-mahjongg aisleriot gnome-mines transmission-common gnome-orca webbrowser-app gnome-sudoku libreoffice-common -y
安装软件包:
apt-get update
有时候需要解决问题,test -w /var/cache/app-info -a -e /usr/bin/appstreamcli;appstreamcli refresh >/dev/null的报错问题

pkill -KILL appstreamcli
apt-get install wget -y
wget -P /tmp https://launchpad.net/ubuntu/+archive/primary/+files/appstream_0.9.4-1ubuntu1_am
wget -P /tmp https://launchpad.net/ubuntu/+archive/primary/+files/appstream_0.9.4-1ubuntu1_amd64.deb https://launchpad.net/ubuntu/+archive/primary/+files/libappstream3_0.9.4-1ubuntu1_amd64.deb
dpkg -i /tmp/appstream_0.9.4-1ubuntu1_amd64.deb /tmp/libappstream3_0.9.4-1ubuntu1_amd64.deb

再apt-get update就不会报上面的错误
apt-get install vim openssh-server sogoupinyin -y

查看系统版本:
cat /etc/issue
其他可选安装:

安装wps

    wget http://kdl.cc.ksosoft.com/wps-community/download/a21/wps-office_10.1.0.5672~a21_amd64.deb
    dpkg -i wps-office_10.1.0.5672~a21_amd64.deb 
由于使用wps有时候会有字符集问题,需要额外的字符集,字符集安装包:我的网盘里。
```

unzip wps_symbol_fonts.zip -d /usr/share/fonts/wps-office
cd /usr/share/fonts/wps-office
chmod 644 ./*
mkfontscale
mkfontdir
fc-cache


解决python占用cpu过高的问题:

add-apt-repository ppa:karl-qdh/ppa
apt-get update
apt-get upgrade
reboot


安装vncserver,实现vnc远程连接ubuntu桌面

apt-get install xfce4
apt-get install vnc4server
apt-get install xrdp
vncserver

编辑.vnc/xstartup文件,如下
cat .vnc/xstartup 
#!/bin/sh
# Uncomment the following two lines for normal desktop:
# unset SESSION_MANAGER
# exec /etc/X11/xinit/xinitrc
#[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
#[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
#xsetroot -solid grey
#vncconfig -iconic &
#x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#x-window-manager &
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
vncconfig -iconic &
xfce4-session &

停止vncserver
`vncserver -kill :1 `  
启动vncserver

vncserver
service xrdp restart
systemctl stop xrdp
systemctl start xrdp


查看是否启动
`netstat -lntup`
然后就可以在windows桌面上使用vnc-client连接了。

安装远程连接windows服务器的系统:
`apt-get install rdesktop -y`
这个需要在ubuntu的桌面上连接,才可以。
rdesktop -f 远程IP
