I upgraded nextcloud 18 to 19.1 I could not pass these errors I ask for your help
The database is missing some optional columns. Due to the fact that adding columns on big tables could take some time they were not added automatically when they can be optional. By running “occ db:add-missing-columns” those missing columns could be added manually while the instance keeps running. Once the columns are added some features might improve responsiveness or usability.
