Description

I get the below error when running ng update --next with pnpm as the configured package manager. It says, the installed CLI is older than the latest published, but it isn't.

Can you please provide the contents of the log file (the file in the error message)?

Thanks

When using —next The latest version is equivalent to the latest next version of the cli.

I think we should improve the message to make it more clear.
