Pacman complains that Haskell libraries require ghc=7.10.2-1
The first thing I did is check what's currently installed:

$sudo pacman -Qi ghc
Name           : ghc
Version        : 7.10.2-1
Packager       : ArchHaskell <arch-haskell@haskell.org>

Looks like I have the right version installed. When I try to install some related packages, however:

$sudo pacman -Sy haskell-ghc-paths haskell-haddock-api haskell-haddock-library haddock
:: Synchronizing package databases...
 xorg116 is up to date
 core is up to date
 haskell-core is up to date
 extra is up to date
 community is up to date
 multilib is up to date
 archlinuxfr is up to date
resolving dependencies...
looking for conflicting packages...
error: failed to prepare transaction (could not satisfy dependencies)
:: haskell-ghc-paths: requires ghc=7.10.2-1
:: haskell-haddock-library: requires ghc=7.10.2-1

This seems completely nonsensical to me. Any ideas?

It's likely that one of your many official repos has updated ghc, but the new version cannot be installed because packages that depend on it have not been updated. As the main repos only have ghc 7.10.1, clearly that is the source of the problem.

Checking that haskell repo reveals that they have two different versions of haskell-ghc-paths in the repo at the same time, that is likely related. Report the error to them. Actually, it looks like they have multiple versions of most packages.

EDIT: scratch that, the biggest problem is that you are doing partial upgrades. This is not supported.

I don't understand. I already have ghc 7.10.2-1 installed, which is exactly the dependency noted by the error message.

ghc 7.10.1 is in the repos https://www.archlinux.org/packages/?name=ghc so probably some packages want to use this version, thus you get an error.

The same happens to me.

:: haddock: requires ghc=7.10.1
:: haskell-haddock-api: requires ghc=7.10.1

This is not a programming & scripting issue. Moving to N.C.

If anyone with this problem wants to post something useful, the un-trimmed output of the following would help:

pacman -Qi ghc

There's the problem:

$ pacman -Si haddock
...
Depends On     : ghc=7.10.1  haskell-ghc-paths  haskell-haddock-api
...

Is there a solution other than waiting for new versions?

Remove haddon, Build your own haddock, request that the unofficial repo add haddock, or stop using the onofficial repo.
