MACCS failed on every downloaded products


I am new (really new) user of Sen2Agri. I managed to install it, I can have access to the graphic interface and add a new site and a season.

By reading some of the posts on the forum, I manage to get some Sentinel2 products downloaded (their status description is on “downloaded” so I assume they are OK).

The MACCS processing begins and then, the status turns to “processing-failed” and the journalctl of demmacs (at some point) returns this:


And I don’t really know what to do with this information.

Thanks in advance for your help.


Hi Audrey,

It looks like the path to MACCS is incorrectly set. It should be /opt/maccs/[...], but right now it’s missing the leading slash.

Wow, such a stupid little mistake… I stared too long at these lines to see it. Thank you so much, Inicola.
