Need to update document to clarify which linux distro that autorest supports now.

I’m trying to use autorest on “WSL 2 + ubuntu” (the default version in Windows Store is “Ubuntu 20.04.1 LTS”)

Autorest does not work on ubuntu 20.04.1 LTS!

autorest --input-file=petstore.yaml --csharp --output-folder=CSharp_PetStore --namespace=PetStore

... 
No usable version of the libssl was found
FATAL: csharp/simplifier - FAILED
FATAL: Error: [Exception] AutoRest extension '@microsoft.azure/autorest.csharp' terminated.
Process() cancelled due to exception : [Exception] AutoRest extension '@microsoft.azure/autorest.csharp' terminated.

This forked repository mentioned that autorest supports up to ubuntu 16.04 https://github.com/amarzavery/AutoRest

I tried ubuntu 16.04, and it works, but have to install another package firstly. (it was also mentioned in amarzavery’s repo) sudo apt-get install libunwind8 -y

So are there any plans to update autorest to use LTS version of .NET?

As far as I understand current version of aurorest is using .NET Core SDK 2.0 which has reached end of life more than 2 years ago in 2018 and is not supported by Microsoft any more. So it means that autorest doesn’t work on Ubuntu 20.04 which is now default version for WSL2 and in Microsoft hosted agents in Azure DevOps.

Thanks for pointing this out, it seems like the current release of @microsoft.azure/autorest.csharp is built with an older .NET Core SDK which expects libssl 1.0 where Ubuntu 20 has libssl 1.1 installed. More info can be found here: https://github.com/dotnet/runtime/issues/28079.

I’ll see if I can get a new build of the generator shipped with a newer update of the SDK.
