src/Error/Error.hs:6:1: error:
     Could not find module ‘Control.Monad.Error’
     Perhaps you meant
       Control.Monad.Co (needs flag -package-id kan-extensions-5.2.6)
       Control.Monad.Free (needs flag -package-id free-5.2)
       Control.Monad.Trans (from mtl-2.3.1)
     Use -v (or `:set -v` in ghci) to see a list of the files searched for.

The above is just how the build ends and not necessarily the most relevant part.
If required, the full build log is available here:

https://people.debian.org/~sanvila/build-logs/202410/

About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

If you could not reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and affects, so that this is still visible in the BTS web
page for this package.

Thanks.
