当我尝试更新时，它说无法下载存储库信息。当我尝试更新时，它挂起并卡住了。
W: The repository 'http://ppa.launchpad.net/upubuntu-com/icons/ubuntu zesty Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch http://ppa.launchpad.net/upubuntu-com/icons/ubuntu/dists/zesty/main/binary-i386/Packages 404 Not Found

您正在查看的 PPA 尚未发布 Zesty，因此更新过程会抱怨找不到您要查找的文件。您可以在以下位置查看可用的版本启动板网站
您应该从软件源中删除此 PPA，直到它被更新 - 执行此操作的命令是
sudo add-apt-repository -r ppa:upubuntu-com/icons
