Upgrading Drupal

Good day,

I have this problem when trying to update drupal 8.6.7 to 8.6.10 by using composer. Before this I try to update manually (replace with drupal core files and folder) but get some error with DBAL module (this module need to be install via composer). For your information, I started drupal project by copying .zip core to server directory, not by using composer. So any other way to update drupal core without having an error with module?

Thanks in advance.

Facing an issue while upgrading from drupal 8.4 to 8.6. 

The website encountered an unexpected error. Please try again later.
Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException: You have requested a non-existent service "access_check.db_update". in Symfony\Component\DependencyInjection\ContainerBuilder->getDefinition() (line 1053 of vendor\symfony\dependency-injection\ContainerBuilder.php).

I have a successful, working install of 8.6.4 and am following the "manual upgrade" notes.  It says to put the site into "Maintenance Mode" but when I do I get an error that "The website encountered an unexpected error. Please try again later."

Anyone know what is going on?  I'm wondering if it's somehow a permissions thing and I need to make myself a higher prived admin...but haven't a clue why I'm not already as high as it goes.

I installed 8.6.4 a few months ago and there've been a number of versions of core that have come out since then.  I want to upgrade, but do I have to do it sequentially?  Like, first do 8.6.4 to 8.6.5, then to 8.6.6, etc., or can I just back things up, overwrite with 8.6.newest, and then copy back in the key parts of settings.php or .htaccess and it should work?

I have tried to get composer working and looked at drush, but for various reasons this isn't working.  Am opting to just do the manual upgrade -- but hoping I don't have to do this one by one by one.

Thank you!

Hey everyone,

I've been going nuts over this. I have drupal 8 setup, and I've got a local instance running.

What I'm seeing though when I try and update the site is:

I run this: composer.phar update --with-dependances

And I get this: don't install drupal/core 8.6.10|remove drupal/drupal dev-feature-LT-14-lmamp-errors

(Please tell me if I am correct that both updating and upgrading are appropriate for this forum, or if updating belongs in post instiallation. Thanks.)

I see that the release notes for 7.6.4 describe a change in settings. This appears to be a narrowly focused change, relevant to people using npm, bower, or composer. I am not.
