[SOLVED] ghc dependency problem

I tried to update this morning my system and got this error message:

sudo pacman -Syu
[sudo] password for david: 
:: Sincronizando las bases de datos de los paquetes…
 core está actualizado
 extra está actualizado
 community está actualizado
 multilib está actualizado

:: Iniciando actualización completa del sistema…

error: no se pudo preparar la operación (no se pudieron satisfacer las dependencias)
:: haskell-deepseq-generics: instalando «ghc» (8.0.1-1) se rompe la dependencia con «ghc=7.10.3»
:: haskell-fail: instalando «ghc» (8.0.1-1) se rompe la dependencia con «ghc=7.10.3»
:: haskell-regex-pcre-builtin: instalando «ghc» (8.0.1-1) se rompe la dependencia con «ghc=7.10.3»

I checked what are these packages for:

pactree -r haskell-regex-pcre-builtin
haskell-regex-pcre-builtin
pactree -r haskell-deepseq-generics
haskell-deepseq-generics
pactree -r haskell-fail
haskell-fail
└─haskell-aeson
  ├─haskell-aeson-pretty
  │ └─haskell-pandoc-citeproc
  ├─haskell-pandoc
  │ ├─haskell-pandoc-citeproc
  │ └─haskell-pandoc-crossref
  ├─haskell-pandoc-citeproc
  ├─haskell-pandoc-types
  │ ├─haskell-pandoc
  │ ├─haskell-pandoc-citeproc
  │ ├─haskell-pandoc-crossref
  │ └─haskell-texmath
  │   └─haskell-pandoc
  └─haskell-yaml
    ├─haskell-pandoc
    ├─haskell-pandoc-citeproc
    └─haskell-pandoc-crossref

and except for the last one, the others two are safe to remove, aren't they?


How can I safely remove haskell-fail without breaking everything else that "apparently" depends on him? A simple "pacman -R haskell-fail" will do it?

Re: [SOLVED] ghc dependency problem

haskell-aeson no longer depends on haskell-fail. Just pacman -Rdd haskell-fail then update.

Re: [SOLVED] ghc dependency problem

I uninstalled them and now I can update.

Thanks Scimmia!
