Thanks for your reply!

Unfortunately, le build log exceed the limit of https://paste.debian.net
However, the "find-crate" crate is installed in the sbuild chroot.

But I noticed that while the name of the crate is "find-crate" (on https://
crates.io) it has to be invokd with find_crate. Could this be a reason?

"find-crate" crate seems built too because in the log there is:
