Hi Yvan,

We had this issue as well, and fixed it for now by adding the checkers.py from an old galaxy server. I've added it in attachment if you don't have it anymore.

put it in "galaxy-dist/lib/galaxy/datatypes/checkers.py"

If relevant, I also made a few changes to the stacks script itself, but I can't remember if is was related (I think due to ordereddict module in different python versions)

Thank you John for the rapid answer and the PR!

I have had the same issue trying installing and use a Galaxy-M instance (https://gigascience.biomedcentral.com/articles/10.1186/s13742-016-0115-8) . I cc Ralf concerning this.

Cheers,

Yvan

Objet: Re: [galaxy-dev] STACKS error

This is one the reasons (though not the only one) I generally
discourage putting datatypes in the tool shed - Galaxy isn't very
clear about what interface it provides to datatypes and it would seem
very difficult from my perspective to maintain that interface and grow
Galaxy at the same time.

This checkers module though is clearly useful to datatypes and it is
quite trivial to provide backward compatibility so I've opened a PR to
the new 16.04 release to restore this module -
https://github.com/galaxyproject/galaxy/pull/2389.

Sorry for the inconvenience.

-John
