That’s weird.

Not sure what you deleted, but should it happen again, you can just leave for 20 mins and come back. Everything would have been reset by then.

I can confirm that command is working fine.

By the way, welcome to the Community!

That’s strange. Did you create any package with the same name? This file should always be present on the VM unless removed.
