我正试图用在Ubuntu上安装ghcup
curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
使用默认选项(prepend to.bashrc，不安装HLS，不安装Stack(。
问题是，当脚本尝试将ghcup-0.0.6.yaml.tmp文件写入~/.ghcup/cache目录时，我收到了一个permission denied错误，我不确定原因。
该目录的权限为1775(drwxrwxr-x(。将它们升级到1777(drwxrwxrwt(并重新运行curl命令会产生同样的错误。目录所有者是我(而不是root(，按照ghcup安装说明的指示，我在没有sudo的情况下运行curl命令。
完整命令输出：

我很想解释一下发生了什么以及如何解决它，这样我就可以开始学习Haskell了！提前谢谢。
已解决：
结果发现snap版本的旋度是半破坏的。运行后，我成功安装了ghcup
sudo snap remove curl
sudo apt install curl
