Я имею, устанавливают.NET Core на моем использовании Ubuntu 18.04 sudo snap install dotnet-sdk --classic, но после завершенного процесса установки, dotnet управляйте все еще работой. Вот мой консольный журнал:

long@long-ub1804:~$ sudo snap install dotnet-sdk
[sudo] password for long: 
error: This revision of snap "dotnet-sdk" was published using classic
       confinement and thus may perform arbitrary system changes outside of the
       security sandbox that snaps are usually confined to, which may put your
       system at risk.

       If you understand and want to proceed repeat the command including
       --classic.
