"The application 'run' does not exist" after updating to 6.0.8 on Ubuntu 22.04

[stoyandimov]

Describe the bug

Running dotnet run (or new or --version) outputs:

The command could not be loaded, possibly because:
  * You intended to execute a .NET application:
      The application 'run' does not exist.
  * You intended to execute a .NET SDK command:
      No .NET SDKs were found.

To Reproduce

Yesterday at the end of the day it was all fine.
This morning, I opened my laptop run apt update and apt upgrade. Version 6.0.8 was installed (and VS Code 1.70.1) and after that I could not run SDK commands anymore.

dotnet --list-sdks returns nothing.
dotnet --info mentions global.json file: Not found

Same issue, Suddenly Jetbrains Rider cannot detect MSBuild after installing the same update in my Linux Mint 21.
The package version is 6.0.8-0ubuntu1~22.04.1. It's weird the version has ubuntu suffix in it.

definately a problem....

That worked.
TBH, not sure what changed, just followed the thread top to bottom, but haven't compared to the official instructions

[longday]

That worked too. #27082 (comment) (Kubuntu 22.04)

[stoyandimov]

The instructions in dotnet/core#7699 solved it for me as well.
