Is there some way I can fix this? I tried removing and reinstalling the haskell-platform package. The weird thing is, even after removing the package, the ghci command seems to be there

[gbaz]

when you say "package" do you mean from your package manager?

There was a known related bug in earlier versions of the 8.2.1 platform. The 8.2.2 platform fixes this, ad well as installing the latest 8.2.1.

[gbaz]

(It looks like you're trying to manage ghc with your package manager, but the version used is from an install of the generic-linux binaries from haskell.org/platform --hence the confusion)

[dwagner-gh]

Can I somehow remove these generic-linux binaries again? I don't know know which version is used by the linux package manager... should I just try to install 8.2.2 so that 8.2.1 is overwritten?

[gbaz]

If you install the new platform over the old one, I think everything should work. Sorry for the inconvenience.

[dwagner-gh]

Thanks a lot man. I reinstalled 8.2.2 from haskell.org/platform using the offered archive. I was getting desperate, but it seems the solution was pretty easy 👍.
