Broken Haskell Platform in 11.04 Depends: ghc6 (< 6.12.1+)

Encountered this bug while trying to install packages for xmonad. Please fix.

Thanks for reporting this issue!

I get the same error message when attempting to install haskell-platform on Ubuntu Natty.

Same issue when trying to install haskell-platform on 11.04 Beta

still broken, I guess I'm on beta2, updated.

Also, the latest version is haskell-platform-2011.2.0.1 and is based on ghc7

Johan: The update is covered in bug 711366.

Well, we certainly need some working version of haskell-platform in natty. Of course 2011.x would be nice (GHC7 has been in debian since January), but I guess that will only show up in natty-backports. We still need a working version in non-backport-natty as well, though, so we can't wait for #711366 if that would mean waiting for half a year.

This bug is still present in the final version of natty:

haskell-platform : Depends: ghc6 (< 6.12.1+) but 6.12.3-1ubuntu7 is to be installed

Why would haskell-platform depend on ghc6 (>= 6.12.1) as well as ghc6 (<< 6.12.1+)?

please fix it immediately

Wouldn't be setting haskell-platform dependency to a proper version of GHC an obvious fix? At least, just to allow users to get their haskell-platform installed properly. I mean, it's been more than a month. Have any unexpected difficulties arisen while fixing this annoying dependency bug?

Workaround: use vi edit the file /var/cache/apt/pkgcache.bin, find the string ' 6.12.1+' and change it to ' 6.12.4+', save

'sudo apt-get install haskell-platform' will still fail while calling some post-install-script, but it seems that haskell-platform is usable now.

I'm not that familiar with building packages, but from looking at the control file, it looks like a simple issue to fix and I've attached a patch. Please test and let me know if it works. Thank you.

I downloaded haskell-platform 2010.2.0.0 and changed the debian's package so that the packages versions match the versions distributed with that version of haskell-platform. Newer versions require ghc7 which is not in ubuntu (it is in debian unstable, so their haskell-platform package is newer, but unapplicable to ubuntu).

You can download it from my PPA:

https://launchpad.net/~brcha/+archive/ppa

The bug is still there, why it takes so long to fix this? It's not funny, some people actually _need_ haskell. Please fix it.

thanks for the ppa @Filip Brcic ...

Natty is available for like 2/3 months and this wasn't yet updated :|

Recent Haskell Platform (2011.2.0.1) with GHC 7 is available in Debian Wheezy. http://packages.debian.org/testing/haskell/haskell-platform

Yes, and it’s also available in Ubuntu oneiric; that was bug 711366, not this bug. This bug is about the uninstallable package in natty.

@Anders Kaseorg: so, why not to fix it in natty?

I'd like to +1 the need for a natty backport or some such.

This looks like a simple fix. Why isn't it applied yet?

I uploaded a fixed package which just removes the version restriction on ghc6 completely. Sorry for the inconvenience.

To test:

 1) Verify the natty haskell-platform package does not install
 2) Verify the natty-proposed one does

No risk of regressions; this is only a meta package.

Oh, and the _darcs stuff in the diff shouldn't have been there in the first place. It's irrelevant. Please ignore it. :-)

Can't find it in natty-proposed - should it show up on https://launchpad.net/ubuntu/+source/haskell-platform or am I doing something wrong?

It isn't accepted yet. Someone will announce on this bug when it is.

All right, thanks!

Hello Gatlin, or anyone else affected,

Accepted haskell-platform into natty-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

I confirm that the version from -proposed installs all right.

Me too! I got it installed and fired up ghci with the -proposed version.

So, what now? When will it make its way from the proposed to an ordinary repository?

yes, next time someone looks at the pending updates, it will be copied into natty-updates, which is enabled by default.

Copied to -updates. This fell off the radar, and wasn't auto-closed, as apparently the sources.changes was misbuilt (missing the Launchpad-Fixes header)
