Upgrade 2.x to 3.x

A workaround is described here:
https://designkojo.com/base-theme-stable9-has-not-been-installed

Basically you need to unhide the stable9 theme in here: web/core/themes/stable9/stable9.info.yml
You need to comment out this line with a hash:
#hidden: true

You should then enable the theme in /admin/appearance
which can also be done using drush I guess.

Hopefully this will survive an upgrade.

Don't forget to run updates. It will uninstall old themes (if present) and enebale stable9
Alternatively run drush updb.
Updating documentation.
If your installation is config driven, don't forget to switch stable and claro to stable9.

The reason I saw this was because the update failed as follows:

> [warning] Post update function bootstrap5_post_update_install_stable9 not found in file bootstrap5.post_update.php
> [error] Update failed: bootstrap5_post_update_install_stable9

The task uninstall_stable_classy therefore did not run

Thanks @chriscant.
Do you have any debug info from php log, Drupal database log or command line?

yes it's working now. drush updb solve my little upgrade.

Thx you!

Hi there

I saw the error when I used "drush updb" at the command line.
However the updates ran OK from the Drupal admin menu in the browser.
And now no updates are required from the command line.
I've never had problems from the command line before.
I don't know what was going wrong, but I seem to be sorted now.

Thanks very much, chris

Cheers @bensti and @chriscant 🥃
@chriscant: might have been cache issue.

Thanks, @chriscant - you were right both times, unhiding stable9 and running update.php instead of drush updb.

I can confirm that running drush updatedb does not work when updating from 3.0@RC to 3.0.2 and results in a warning and error:

>  [warning] Post update function bootstrap5_post_update_install_stable9 not found in file bootstrap5.post_update.php
>  [error]  Update failed: bootstrap5_post_update_install_stable9

.

However, running updates from the Drupal Admin menu in the browser works without any warnings or errors (same as it was reported by @chriscant ).

Clearing caches does not help to resolve the issue with drush updatedb.

In my case the issue was with drush 10. Using drush 11 the update worked.

Probably related to: https://github.com/drush-ops/drush/pull/5120
and https://www.drupal.org/project/drupal/issues/3259188 →

Just some small recommendations:

If your installation is config driven, don't forget to switch stable and claro to stable9

@VladimirAus you should probably declare for follow up readers what you refer to by "config driven" and "switch" - The context isn't obvious. Just a thought.

Apart from that: @all remember that making stable9 visible is a "hack" and not intented. There is surely a reason for that core has it hidden by default. If sth is not working with stable9 being hidden and if it is a bug, then it should be proper reported depending on where this bug has been caused, maybe core, maybe Bootstrap5 or somewhere else. But this work around here is not a fix of an issue, it is just a work around hiding an underlying problem.

Thanks for suggestion.
It is part of help now: https://www.drupal.org/project/bootstrap5#upgrade3 →

Automatically closed - issue fixed for 2 weeks with no activity.

I'm getting this error when running drush updb on a fresh instance of Drupal 10.1.2. I'm using drush 12.1. As mentioned before unhiding stable9 should not be the correct way to fix this issue.

@bajah1701
Do you have error log? Please share if you do.

1. Clear cache
2. Run drush pm:list | grep -E "stable|classy" should result something like

  Core                                Stable 9 (stable9)                                                                      Enabled    10.1.2          
  Core                                Classy (classy)                                                                         Disabled   1.0.2           
  Core                                Stable (stable)                                                                         Disabled   2.0.0

3. If now, uninstall classy and stable and enable stable9.

drush theme:install stable9
drush theme:uninstall stable classy

@VladirmirAus
