我无法安装 curl

我想安装Brave浏览器,但是无法安装curl。

E:软件包‘curl’没有安装候选项

上一个问题建议我切换到另一个 ubuntu 镜像。我切换到了最好的服务器,但什么都没有改变。

Package curl is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'curl' has no installation candidate

更新后得到以下结果:

Kulfy,谢谢你。我必须先运行这些行,然后才能安装

apt remove -y libcurl4
apt install -y libcurl4 curl

这是您的存储库的问题,curl在 Ubuntu 主目录中可用。您需要更新您的存储库。打开终端并运行

nano /etc/apt/sources.list

更新您的存储库并运行

sudo apt-get update
sudo apt-get install curl
