Route "update.theme_install" does not exist

Hi @mugesh.s,

I have set up Drupal 11 on my system and have not encountered this issue. Could you please provide detailed steps to reproduce it? Additionally, let me know if there are any specific configurations or modules involved that might be contributing to the problem.

Hi @kushagra.goyal

This issue is encountered in Drupal versions lower than 11, I faced it in 10.4.0. After installing the module, navigating to the admin menu (/admin/structure/menu/manage/admin) resulted in this error. When applying the patch the issue got fixed and might work only in versions lower than 11.

Patch #4, fixed the issue.

I am working here.

Issue : This issue clearly depends on the Update Manager module when using both the Update Manager and Admin Toolbar together

To reproduce the issue in Drupal 10.4.2 or above:

1. Administration > Extend : Enable Admin Toolbar , Admin Toolbar Extra Tools and Update Manager
2. Structure > Menu > Administration , Click edit menu

Root cause :
File path :web/modules/contrib/admin_toolbar/admin_toolbar_tools/src/Plugin/Derivative/ExtraLinks.php : line 489 and 501

1. Drupal 10.4.x does not have the update.theme_install route name, while it was there in Drupal 10.3.x. and below
2. The error encountered is due to the condition if (version_compare(\Drupal::VERSION, '11.0.0', '<')).

solution :
Change the condition if (version_compare(\Drupal::VERSION, '10.4.0', '<')) to make it work.

Use this patch to fix the issue as mentioned in comment#11.

Looks like issue introduces in 10.4+ so I changed 11.0 to 10.4
attaching patch admin_toolbar.patch (1.29 KB)

Thanks, this was already reported in another issue.
