我按照以下指示進行操作這裡從 Ubuntu feed 安裝 .NET 6 SDK 後安裝 .NET 7 SDK。
wget https://packages.microsoft.com/config/ubuntu/22.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
rm packages-microsoft-prod.deb
sudo apt-get update && sudo apt-get install dotnet-sdk-7.0結果出現此錯誤：
Reading package lists... Done

Reading state information... Done
Package dotnet-sdk-7.0 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 'dotnet-sdk-7.0' has no installation candidate
sudo apt show dotnet-sdk-7.0 -a結果是這樣的：
