Request for Debian bullseye/stable-based images

[jmtd]

Debian 11 "bullseye" came out in August 2021, and at that point stable came to mean Bullseye, and oldstable to mean Buster.

hub.docker.com/_/haskell says

we support the two most versions of Debian (stable and oldstable) as variants

This is currently not correct. Please consider providing bullseye-based images. Thanks!

It seems cabal-install and ghc provide Debian 10 binaries but not yet 11.

Yep, my understanding is it will come 'soon' based on the work around https://gitlab.haskell.org/ghc/ghc/-/issues/21002 . Not sure about the cabal side of things, but presumably if GHC is providing it cabal will also follow suit.

9.4.1 support amd64 deb11, however aarch64 support is not yet included. The images need to support both processor architectures, so we will need to wait. deb11 aarch64 support is scheduled for 9.4.3.

[AlistairB]

cabal 3.8 does not support deb11 unfortunately. If someone is motivated they could raise the issue with the cabal folk.

I created haskell/cabal#8376

EOL of Buster is approaching, so this should probably be prioritized.
Cabal seems to support Debian 11 now?: https://downloads.haskell.org/~cabal/cabal-install-latest/

Any more blockers?

No longer a maintainer, but I think GHC is still not providing deb11 for aarch64 https://downloads.haskell.org/~ghc/9.8.1/ . Perhaps it will come with 9.10.1 https://gitlab.haskell.org/ghc/ghc/-/issues/22005

[jmtd]

Pleased to see deb11 builds have appeared at https://downloads.haskell.org/~ghc/9.10.1-alpha1/
However current debian stable is now Debian 12 ("bookworm").
