AssertionError: <class 'trytond.pool.stock.configuration.sequence'> has no docstring

Hello everyone,

I’m trying to upgrade from 4.2 to 5.0, so I followed the migration steps:

Then to upgrade the new series, I run the command line (trytond-admin -c <config file> -d <database name> --all) and a dependency error happens:

(env) connecttix@ip-172-26-6-37:~/tryton$ ./trytond/bin/trytond-admin -c ./conf/trytond.conf -d connecttix_tryton --all
Traceback (most recent call last):
  File "./trytond/bin/trytond-admin", line 21, in <module>
    admin.run(options)
  File "/home/connecttix/tryton/trytond/trytond/admin.py", line 54, in run
    activatedeps=options.activatedeps)
  File "/home/connecttix/tryton/trytond/trytond/pool.py", line 160, in init
    lang=lang, activatedeps=activatedeps)
  File "/home/connecttix/tryton/trytond/trytond/modules/__init__.py", line 418, in load_modules
    _load_modules(update)
  File "/home/connecttix/tryton/trytond/trytond/modules/__init__.py", line 382, in _load_modules
    graph = create_graph(module_list)
  File "/home/connecttix/tryton/trytond/trytond/modules/__init__.py", line 159, in create_graph
    raise MissingDependenciesException(list(missing))
trytond.exceptions.MissingDependenciesException: Missing dependencies: stock_package_shipping

So, to fix that error, I ran next command line: (trytond-admin -c <config file> -d <database name> -u <module name> --activate-dependencies), without any success:

(env) connecttix@ip-172-26-6-37:~/tryton$ ./trytond/bin/trytond-admin -c ./conf/trytond.conf -d connecttix_tryton -u stock_package_shipping --activate-dependencies

  • Could anyone tell me what’s wrong?
  • What can I do to fix it?

It seems like you are missing the stock_package_shipping module in your trytond/modules path.

@formateli No, It is installed

Have you updated the modules in each version upgrade?

There is a module that adds the ‘stock.configuration.sequence’ model which is missing the DocString.

You should set the docstring or remove the module (if you do not use it) that has declared this model.
