Hi @Alex M.ach​ 

Indeed, the cups package is not shipped into the OpenSTLinux repository because of some installation errors that corrupt the dpkg database.

Could you tell me which ecosystem (v1.2, v2.0, v2.1 or v3.0) you are using please so I can try to make some attempts?

Best regards

Hello @Alex M.ach​ 

I just updated the OpenSTLinux distributions V3.0 and V2.1 so the cups package is now available.

These are the commands to perform on your board.

Firstly, you need to update the package database:

You can now run some tests to check the package is well installed:
