concretecms: Cant upgrade from 8.1 to 8.2.1

I followed the manual steps:

Download the latest core from http://www.concrete5.org/download
Unzip the file. Remove all contents except the concrete directory.
At this point you should have a folder named something like concrete5.7.x.x, with only a “concrete” directory inside it.
Move the concrete5.7.x.x folder into your updates/ directory.
Head to Dashboard > System and Settings > Update Concrete5. The update should be listed, and you can click through to update to the latest version.

And then, I got this: Class 'Symfony\Component\Form\AbstractTypeExtension' not found in application/src/Form/Extension/HelpTextExtension.php13

Any idea?

I just edited that documentation page by specifying that also the composer.json and composer.lock files should be replaced (you have to wait until the core team approves my changes).

Updating the documentation is an easy operation that everyone can do; you ave just to

go to https://documentation.concrete5.org
click the Sign In link and login
click the Edit Page you find bottom right

@aembler What about showing the Edit Page button even for guests? That way, everyone can know they can contribute (like the Translate button you can find at https://translate.concrete5.org/translate/package/concrete5: if clicked when you are not logged in, concrete5 will automatically bring you to the login page - but I guess you already know how it works 😉)
