升级

V71(或者更老版本)升级至V77使用apt-get dist-upgrade
V76升级至V77使用apt-get upgrade

ps：如果想将emulatedlab源修改为官方源，输入

sudo add-apt-repository "deb [arch=amd64] http://www.eve-ng.net/repo xenial main"

使用这里跨多个版本升级，输入

root@eve-ng:~# apt-get dist-upgrade

root@eve-ng:~# reboot

修复无法登陆

浏览器登陆eve-ng，登陆页面闪烁，或者一直提示正在载入，强行清理浏览器缓存Ctrl+F5，如果还打不开，下载使用emulatedlab.com出的EVE-NG定制Toolkit工具

wget https://www.vos.cn/nexus/eve_ng_toolkit.tgz -O eve_ng_toolkit.tgz&&tar zxvf eve_ng_toolkit.tgz&&./eve_ng_toolkit.sh

选择5，进行FIX permissions，之后浏览器再测试就可以打开了

跨版本升级提示有多余包
