答案1
如果第一个命令出现错误,则不会执行“&&”后面的命令。请改用 || 或 ;。(请参阅https://stackoverflow.com/questions/4510640/command-line-what-is-the-purpose-of)
因此更新后(使用 sudo apt-get update),只需执行
sudo apt-get upgrade
或者
sudo apt-get dist-upgrade
在另一行/命令上(如果您不想使用 || 或 ;)。您还应该验证您的源列表是否仍然有效(以消除 apt-get update 命令中的错误,以便您可以执行 &&,并使其运行得更快)- 因此请检查源 URL 的所有警告“W:”并确保它们是最新的;如果它们已停用,只需将它们从您的软件源中删除即可。
编辑:要删除软件源(我假设您使用 Unity):
转到软件中心 > 编辑 > 软件源(或运行“software-properties-gtk”)。
然后向下滚动“软件源”选项卡并取消选中给您带来麻烦的存储库。(如果您仍然想要来自这些存储库的软件,则应添加新的更新存储库。对于 Xorg Edgers,请查看并阅读https://launchpad.net/~xorg-edgers/+archive/ubuntu/ppa)。

我在笔记本电脑上安装 Ubuntu 操作系统后也遇到了同样的情况。试试这个。
打开终端并输入以下命令并执行。
sudo apt-get 更新
