Hi , last two weeks I run Roslynator cli 0.8.9 and it worked fine. However , its failed when I try to run it today.
I tried to upgrade to roslynator cli version 0.9.0 but still received the same error.

the error message :
exit status 1: The tool package could not be restored.
Tool 'roslynator.dotnet.cli' failed to install. This failure may have been caused by:

• You are attempting to install a preview release and did not use the --version option to specify the version.
• A package by this name was found, but it was not a .NET tool.
• The required NuGet feed cannot be accessed, perhaps because of an Internet connection problem.
• You mistyped the name of the tool.

I was forced to drop support for .NET 6 SDK to be able to update to latest Roslyn version which does not support .NET 6. More info can be found here: #1483

You can either stay or 0.8.9 or install .NET 7 or 8 SDK on your environment. If you use Roslynator CLI in you GH pipeline it should be possible to upgrade to .NET 7 or 8 SDK unless there are some specific reasons why to use .NET 6.
