I'm working on Mac OS 10.13.6 and want to snap a python script. To build it for amd64 is not a problem but now I want to build it for armhf. So I tried it with remote-build: snapcraft remote-build --build-on=armhf All data sent to remote builders will be publicly available. Are you sure you want to continue? [y/N]: y snapcraft remote-build is experimental and is subject to change - use with caution. Sorry, an error occurred in Snapcraft: name '_source_handler' is not defined Traceback (most recent call last): File "/usr/local/bin/snapcraft", line 8, in <module> sys.exit(run()) File "/usr/local/Cellar/snapcraft/3.11/libexec/lib/python3.7/site-packages/click/core.py", line 829, in __call__ return self.main(*args, **kwargs) File "/usr/local/Cellar/snapcraft/3.11/libexec/lib/python3.7/site-packages/click/core.py", line 782, in main rv = self.invoke(ctx) File "/usr/local/Cellar/snapcraft/3.11/libexec/lib/python3.7/site-packages/click/core.py", line 1259, in invoke return _process_result(sub_ctx.command.invoke(sub_ctx)) File "/usr/local/Cellar/snapcraft/3.11/libexec/lib/python3.7/site-packages/click/core.py", line 1066, in invoke return ctx.invoke(self.callback, **ctx.params) File "/usr/local/Cellar/snapcraft/3.11/libexec/lib/python3.7/site-packages/click/core.py", line 610, in invoke return callback(*args, **kwargs) File "/usr/local/Cellar/snapcraft/3.11/libexec/lib/python3.7/site-packages/snapcraft/cli/remote.py", line 161, in remote_build package_all_sources=package_all_sources, File "/usr/local/Cellar/snapcraft/3.11/libexec/lib/python3.7/site-packages/snapcraft/cli/remote.py", line 188, in _start_build repo_dir = wt.prepare_repository() File "/usr/local/Cellar/snapcraft/3.11/libexec/lib/python3.7/site-packages/snapcraft/internal/remote_build/_worktree.py", line 322, in prepare_repository part_config = self._process_part_sources(part_name, part_config) File "/usr/local/Cellar/snapcraft/3.11/libexec/lib/python3.7/site-packages/snapcraft/internal/remote_build/_worktree.py", line 241, in _process_part_sources part_config["source"] = self._pull_source(part_name, source) File "/usr/local/Cellar/snapcraft/3.11/libexec/lib/python3.7/site-packages/snapcraft/internal/remote_build/_worktree.py", line 163, in _pull_source source_handler = self._get_part_source_handler(part_name, source, download_dir) File "/usr/local/Cellar/snapcraft/3.11/libexec/lib/python3.7/site-packages/snapcraft/internal/remote_build/_worktree.py", line 93, in _get_part_source_handler source, source_type=source_type File "/usr/local/Cellar/snapcraft/3.11/libexec/lib/python3.7/site-packages/snapcraft/internal/sources/__init__.py", line 170, in get_source_handler return _source_handler[source_type] NameError: name '_source_handler' is not defined We would appreciate it if you created a bug report at
