Problem : EVE-PRO Rollback to EVE Community

[jjc1984]

I'd like to do a Rollback from EVE-PRO to EVE-Community (license expired and right now im not using eve pro features like docker)

I have a problem following the steps to rollback to eve community. Basically non pro packages aren't available. Any clue how to fix that ?
