Hello, I pushed my code here

git clone https://salsa.debian.org/picca/pkg-haskell-tools

to reproduce the issue

create a p directory in the repository
cd pkg-haskell-tools
mkdir p
cd p && apt source ufo-core
cd ..
cabal run make-all -- --unshare

With no chroot under ~.cache/sbuild/ so sbuild need to create a new one.

With a prebuild schroot it works...
