stack ls snapshots usage

[cybaj]

I don't know it is issue or not proper command usage, when I stack ls snapshots,
it shows up with just hash-like strings.

Is it something wrong or just not proper command usage?

other things, which are, I think, basic, new, build, exec, run etc works fine.
stack ls dependencies works fine, too.

$ stack ls dependencies
array 0.5.4.0
base 4.13.0.0
containers 0.6.2.1
deepseq 1.4.4.0
ghc-prim 0.5.3
integer-gmp 1.0.2.0
parallel 3.2.2.0
rts 1.0

That's definitely a bug. It behaviour should be like this: https://github.com/commercialhaskell/stack/pull/3252

@psibi unfortunately that behavior was broken by the main change introduced in Stack 2 - implicit snapshots, I'm not sure how old behavior of local snapshots command could be restored to the one that was there in version 1.
BTW remote snapshots are clearly broken as well:

$ stack ls snapshots remote

@qrilka Thanks for the info. It seems with @snoyberg 's change here https://github.com/fpco/stackage-server/issues/292#issuecomment-641051503 , the remote snapshots has started to work again:

$ stack ls snapshots remote
