安装Mastodon时系统所需要的依赖时遇到的问题

不是很了解ubuntu的命令，安装mastodon官方的教程到这一步时

apt install -y \   imagemagick ffmpeg libpq-dev libxml2-dev libxslt1-dev file git \   g++ libprotobuf-dev protobuf-compiler pkg-config nodejs gcc autoconf \   bison build-essential libssl-dev libyaml-dev libreadline-dev \   zlib1g-dev libncurses5-dev libffi-dev libgdbm-dev \   nginx redis-server redis-tools postgresql postgresql-contrib \   certbot python-certbot-nginx yarn libidn11-dev libicu-dev libjemalloc-dev

遇到如下问题

Reading package lists... Done

E: Unable to locate package

在运行之前，已按照官方教程更新了系统包，请各位帮我解解迷津

提前致谢！
