How can fixed this error in moodle update?

Question

HelloW!

When I went to upgrade moodle 3.10 to 3.11 and later 4.x.

I got a problem, after installing all the plugins that weren't on disk, and others that weren't found.

When proceeding, I had this image error.

I installed all the missing plugins on the disk given in the update.

I downloaded and installed the PT-BR Moodle 3.11 language pack in the lang folder and also cleared the cache of the folders inside moodledata in my case it has another name. But i don't delete lang folder in moodledata and exist content in this folder. path moodledata: /var/AnotherName

I updated the system, ubuntu, entered the permissions in the folder again and nothing worked until now.

I kept the config.php from the old moodle as recommended. The only warning I got in the update was about input_vars below 5000, and about the database not being in exact moodle format. But it was just warnings.

Check that in your function xmldb_plugin_name_upgrade($oldversion) you have a final line that returns a true value.

That is: return true at the end of the function.
