Can't build the website locally

[George Karachalias]

I'm failing to build the website for local hacking on Ubuntu 20.04.4 LTS, due to the following error:

$ cd src
$ ./hack 
+ echo 123
+ stack run -- clean
Preparing to install GHC (tinfo6) to an isolated location.
This will not interfere with any system-level installation.
Downloaded ghc-tinfo6-8.4.4.                                      
rts-1.0: Warning: .:466:1: The field "hugs-options" is deprecated. hugs isn't supported anymore
Installed GHC.    
ghc: panic! (the 'impossible' happened)
  (GHC version 8.4.4 for x86_64-unknown-linux):

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

Might it be the case that we need to pin a different GHC version?

wow; this is unfortunate

i believe from monoidal i've learned that this means you need to delete your .stack folder; but this really shouldn't happen with stack :(

@silky indeed, purging .stack worked! Pity that these things still happen, but I'll go ahead and close the issue anyway; not much we can do about it here.
