我收到此错误,不知道如何解决问题：
After updating your package information,the essential package
‘ubuntu-minimal’ could not be located. This may be because you have
no official mirrors listed in your software sources,or because of
excessive load on the mirror you are using. See /etc/apt/sources.list
for the current list of configured software sources.
In the case of an overloaded mirror,you may want to try the upgrade
again later.
任何人都可以告诉我需要做什么.
我在
https://askubuntu.com/questions/124017/how-do-i-restore-the-default-repositories的帮助下重建了我的/etc/apt/sources.list.我的sources.list有一些自定义的和Linode镜像.我刚刚用
https://repogen.simplylinux.ch的输出替换了我的sources.list.我再次运行升级并且成功了.
