@woffs Thanks for sending this fix.

amqp actually looks like it will get bumped to 0.19 for the upcoming LTS-15, which should mean that you don't have to override amqp:

#79819

Can you rebase this on haskell-updates and remove the override?

Also, for future reference, the hackage-packages.nix file is generated automatically, so please don't edit it.

Also, if you were willing to put amqp-utils in stackage, that would mean it would most likely continue working in the future without having to do anything special in nixpkgs.

Thank you @cdepillabout . https://www.stackage.org/lts-15.0 lists amqp-0.19.1, but configuration-hackage2nix.yaml in haskell-updates is still LTS-14.25 with amqp-0.18.3 listed. Maybe I only need to wait some hours until this is updated to LTS-15.0 and my PR can be closed anyway?

And I was not aware that I could put my package into stackage, and I will find out how to do this. Thank you for the hint!

Maybe I only need to wait some hours until this is updated to LTS-15.0 and my PR can be closed anyway?

Yeah, I think you will only need to wait a few days until that PR actually updates to LTS-15.0.

After that happens, please send another PR to the haskell-updates branch marking amqp-utils as non-broken.

amqp-utils now builds fine on haskell-updates and is marked non-broken already.
Will LTS-15.0 go into nixos-20.03 as well or id the dependency to be fixed manually for 20.03?

LTS-15.0 go into nixos-20.03

Yeah, peti is planning on doing this.
