Build fails at "Using CondaBuildPack builder"

Hi folks,

The build for Binder is failing (“Error loading uds-se/fuzzingbook/master!”) at “Using CondaBuildPack builder” without a specific error message in the log (see below).

Running repo2docker -v '.:.' . locally (as suggested) works without producing any errors.

The fuzzingbook repo is big and normally takes several minutes to build both in mybinder as well as in repo2docker (with progress stalling at “Using CondaBuildPack builder” for several minutes, too), but has been running without problems for the last four years. Any help will be appreciated.

Cheers - Andreas
