source.list中含有https
所以在更换源之前安装
apt-get install apt-transport-https
然后更换为中科大的源貌似不行
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse
再更换为清华的源
deb https://mirror.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic main restricted universe multiverse
deb-src https://mirror.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic main restricted universe multiverse

deb-src https://mirror.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-proposed main restricted universe multiverse
#deb [arch=arm] http://dl.google.com/linux/chrome/deb/ stable main
wget -q -O - https://dl.google.com/linux/linux_signing_key.pub | apt-key add -
先建立文件夹sources.list.d
sh -c 'echo "deb http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google-chrome.list'
后来发现是debian系统
将sourcelist改为
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ jessie main contrib non-free
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ jessie main contrib non-free
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ jessie-updates main contrib non-free
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ jessie-updates main contrib non-free
#deb https://mirrors.tuna.tsinghua.edu.cn/debian/ jessie-backports main contrib non-free
#deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ jessie-backports main contrib non-free
#deb https://mirrors.tuna.tsinghua.edu.cn/debian-security jessie/updates main contrib non-free
#deb-src https://mirrors.tuna.tsinghua.edu.cn/debian-security jessie/updates main contrib non-free
deb http://downloads.sourceforge.net/project/ubuntuzilla/mozilla/apt all main
再后来查到chrome不支持arm，只有chromium支持arm，但是不能放视频。
火狐也装不上，只好装了一个firefox-esr。
至于能不能放视频，
