Updating Drupal 9 core with Composer

Introduction

This post is a sequel to my past story where I succeeded in getting "Available updates" in admin panel of Drupal.

Fix Drupal's "Failed to get available update data" error on Available updates

#drupal #update #security #troubleshooting

Body

Event

It recommended updating to 9.1.9 because of a security vulnerability 9.1.8 today.
However, there was none of auto core update.
Therefore, I tried to update it manually. It was my first Drupal core update with update.php via a web browser instead of drush commands.

Besides, when drush is installed with Drupal, there is a way to update database with it:

Updating Drupal with Composer

#drupal #update #composer #drush

Operation

Connect to the server via SSH.
Move to Drupal directory:

$ cd <drupal-dir>

It is able to check outdated packages beforehand:

$ composer outdated
...
drupal/core                          9.1.8   9.1.9   Drupal is an open source content man...
...

Then, update drupal/core + its dependencies only.

$ composer update drupal/core "drupal/core-*" --with-all-dependencies
Loading composer repositories with package information
Updating dependencies
Lock file operations: 0 installs, 6 updates, 0 removals
  - Upgrading drupal/core (9.1.8 => 9.1.9)
  ...

Optionally (and maybe not being recommended), it's also able to update all:

$ #composer update

Next, if drush exists, drush update is available.
But, in my case, it doesn't.
Alternatively, I opened https://<fqdn>/update.php in my web browser, following the official documentation, Drupal - Updating Drupal core via Composer.
Said, "Drupal database update"!

Happily, there was nothing to do that time.

Conclusion

The status report became healthy again, saying "Up to date ✅"🙂
