Installing Powershell and .NET 6 on Ubuntu 22.04 (Jammy)

We announced support for .NET 6 on Ubuntu 22.04 with our May 2022 Updates. At that time, the supported installation methods were manual installation via a tarball or a .deb package via packages.microsoft.com (PMC). .NET 6 is now available natively via Jammy feeds, which can cause conflicts with PMC feeds.

For specifics on installation of just .NET 6, see issue #7699
