I'm not able to install papermerge on fresh Ubuntu 20.04 Server, i see always the following error when i invoke manage.py and have no idea how i can fix this:

(.venv) me@papermerge:/opt/papermerge$ ./manage.py migrate Traceback (most recent call last): File "./manage.py", line 24, in <module> execute_from_command_line(sys.argv) File "/opt/papermerge/.venv/lib/python3.8/site-packages/django/core/management/__init__.py", line 401, in execute_from_command_line utility.execute() File "/opt/papermerge/.venv/lib/python3.8/site-packages/django/core/management/__init__.py", line 395, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/opt/papermerge/.venv/lib/python3.8/site-packages/django/core/management/base.py", line 330, in run_from_argv self.execute(*args, **cmd_options) File "/opt/papermerge/.venv/lib/python3.8/site-packages/django/core/management/base.py", line 371, in execute output = self.handle(*args, **options) File "/opt/papermerge/.venv/lib/python3.8/site-packages/django/core/management/base.py", line 85, in wrapped res = handle_func(*args, **kwargs) File "/opt/papermerge/.venv/lib/python3.8/site-packages/django/core/management/commands/migrate.py", line 75, in handle self.check(databases=[database]) File "/opt/papermerge/.venv/lib/python3.8/site-packages/django/core/management/base.py", line 392, in check all_issues = checks.run_checks( File "/opt/papermerge/.venv/lib/python3.8/site-packages/django/core/checks/registry.py", line 70, in run_checks new_errors = check(app_configs=app_configs, databases=databases) File "/opt/papermerge/.venv/lib/python3.8/site-packages/papermerge/core/checks.py", line 110, in binaries_check binary = os.path.basename(binary_path) File "/usr/lib/python3.8/posixpath.py", line 142, in basename p = os.fspath(p) TypeError: expected str, bytes or os.PathLike object, not NoneType

I followed the Installation guide found here. Any Ideas what is missing here?

Thanks for quick heads up!

It is a nasty bug. Here is workaround:

1.First install dependencies:

$ pip3 install -r requirements/base.txt

Check installation path of stapler utility with

$ which stapler

Add that path (absolute path to stapler utility) to papermerge.conf.py:

BINARY_STAPLER = "/home/eugen/Lab/DMS/.venv/bin/stapler"

Fixed. I added default value for stapler.
If you will get latest source code (via git pull command), it should work without workaround.

@ciur commented on GitHub (Mar 12, 2021): Fixed. I added [default value for stapler](https://github.com/ciur/papermerge/commit/3da0f26274d5e0a0f6e6c7be0171c550d929b9f5). If you will get latest source code (via ``git pull`` command), it should work without workaround.

I use docker (want to test papermerge for the first time)

should your solution work for me?
where can I see error.log?
where is the requirements folder?
where is papermerge.conf.py?

Thank you.
