The SHA1SUMS and SHA256SUMS files in https://downloads.haskell.org/~ghc/8.2.2/ do not have checksums for ghc-8.2.2-x86_64-unknown-linux.tar.xz .

Thanks for noticing this. Fixed.

Unfortunately it looks like it is only a partial fix. Some missing checksums have been added but there are still none in either file for ghc-8.2.2-x86_64-unknown-linux.tar.xz . Regards, Jeremy Henty
