使用 do.net-install 脚本在 Ubuntu 上安装 .Net sdk 时权限被拒绝

Question

我在usr/share/do.net下安装了一些 .Net sdks，我正在尝试在同一位置使用do.net-install.sh安装新版本，如下所示：

dotnet-install.sh --install-dir /usr/share/dotnet --no-path

即使我已经chmod +x脚本，安装仍然会记录权限被拒绝的问题。

dotnet-install: Note that the intended use of this script is for Continuous Integration (CI) scenarios, where:
dotnet-install: - The SDK needs to be installed without user interaction and without admin rights.
dotnet-install: - The SDK installation doesn't need to persist across multiple CI runs.
dotnet-install: To set up a development environment or to run apps, use installers rather than this script. Visit https://dotnet.microsoft.com/download to get the installer.

dotnet_install: Error: Failed to verify the version of installed `.NET Core SDK

我在这里错过了什么？

我建议使用 sudo 运行 do.net-install.sh 脚本。
或者将 do.net-install.sh 标记为可执行文件： sudo chmod +x./do.net-install.sh 。
