ng update results in npm ERR! Could not resolve dependency

[egnexstep]

I have a angular project I created last week, running Angular 11.2.25 and I thought I would update to the latest version ( I see that the latest version now is 11.2.6 for core)

Running ng update, shows:

The installed local Angular CLI version is older than the latest stable version.
Installing a temporary version to perform the update.
Installing packages for tooling via npm.
Installed packages for tooling via npm.
Using package manager: 'npm'
Collecting installed dependencies...
Found 35 dependencies.
We analyzed your package.json, there are some packages to update:

  Name                               Version                  Command to update
 --------------------------------------------------------------------------------
  @angular/cli                       11.2.4 -> 11.2.5         ng update @angular/cli
  @angular/core                      11.2.5 -> 11.2.6         ng update @angular/core

There might be additional packages which don't provide 'ng update' capabilities that are outdated.
You can update the additional packages by running the update command of your package manager.

And then running ng update @angular/cli just shows me this:

Shouldn't this just work or am I missing something? (I also tried using --force, with the same result...)

Which version of NPM 7 are you using?

If you are not using 7.6 or later, kindly update.

[egnexstep]

I am using npm version 7.6.3

This seems like a duplicate of #20180 where it looks like an NPM defect as 11.2.6 does satisfy ^11.0.0 || ^11.2.0-next but NPM is saying it does not.
