Description:

ipfs pin update $cidA $cidA
gives no error and even states the update was successful even though $cidA is not pinned.
As opposed to
ipfs pin update $cidA $cidB
where you get the error 'from' cid was not recursively pinned already

Relevant issue #6648

Seems reasonable, open to a PR.

Out of curiosity are you relying on an error from ipfs pin update $cidA $cidA or is it just something you ran into?

[Kycklingar]

I was relying on the error. Luckily I caught it early on and fixing was straight forward.
Still I expect a pin update of an unpinned cid to fail.

@Kycklingar This is fixed in v0.8.0-rc1.
