GHCI freaked out when I tryed to load a program and told me to report it as a bug.

ghc: panic! (the 'impossible' happened)

(GHC version 8.0.2 for x86_64-unknown-linux):

initTc: unsolved constraints

WC {wc_insol = [W] %_a2g7 :: t_a2g6[tau:1] (CHoleCan: %)}

Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug

Thanks for the bug report. This is a duplicate of #13106 (closed), which has been fixed in GHC 8.2.1.

Alright cool. I ran $sudo apt-get update and then tried to reinstall ghc, but it gave me 8.0.2 again. When will the updated version be available from this repository? If it isn't going to be soon how else can I download it?

That's up to the people who maintain your Linux distribution—we aren't the ones who do that.

If it isn't going to be soon how else can I download it?

You can find binary distribution of GHC 8.2.1 here. Alternatively, if you use Ubuntu, you can also obtain GHC 8.2.1 from this Ubuntu PPA.
