Internal Server Error after Upgrade to 11.0.1

I have used Nextcloud for several months without problems, but still used version 9. So today, I upgraded using the web updater, going through version 10 to 11.0.1. The upgrade ran without any problems, but after reloading the Nextcloud instance I keep getting an internal server error:

Internal Server Error
The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.

Lighttpd does not show any errors, so I am pretty much at a loss. Any ideas what’s going wrong here?? Any help would be hightly appreciated.

I did find some information in the Nextcloud logfile in the data directory, but I don’t understand it.

ownCloud[6316]: {index} Exception: {“Exception”:“OCP\Files\NotFoundException”,“Message”:"",“Code”:0,“Trace”:"#0 /var/www/nextcloud/lib/private/Files/Node/Node.php(223): OC\Files\Node\Node->getFileInfo()\n#1 /var/www/nextcloud/lib/private/Files/Node/Node.php(106): OC\Files\Node\Node->getPermissions()\n#2 /var/www/nextcloud/lib/private/Files/Node/Folder.php(144): OC\Files\Node\Node->checkPermissions(4)\n#3 /var/www/nextcloud/lib/private/Files/AppData/AppData.php(112): OC\Files\Node\Folder->newFolder(‘admin’)\n#4 /var/www/nextcloud/lib/private/AvatarManager.php(100): OC\Files\AppData\AppData->newFolder(‘admin’)\n#5 /var/www/nextcloud/lib/private/TemplateLayout.php(115): OC\AvatarManager->getAvatar(‘admin’)\n#6 /var/www/nextcloud/lib/private/legacy/template.php(232): OC\TemplateLayout->__construct(‘user’, ‘files’)\n#7 /var/www/nextcloud/lib/public/AppFramework/Http/TemplateResponse.php(157): OC_Template->fetchPage()\n#8 /var/www/nextcloud/lib/private/AppFramework/Http/Dispatcher.php(113): OCP\AppFramework\Http\TemplateResponse->render()\n#9 /var/www/nextcloud/lib/private/AppFramework/App.php(114): OC\AppFramework\Http\Dispatcher->dispatch(Object(OCA\Files\Controller\ViewController), ‘index’)\n#10 /var/www/nextcloud/lib/private/AppFramework/Routing/RouteActionHandler.php(47): OC\AppFramework\App::main(‘ViewController’, ‘index’, Object(OC\AppFramework\DependencyInjection\DIContainer), Array)\n#11 [internal function]: OC\AppFramework\Routing\RouteActionHandler->__invoke(Array)\n#12 /var/www/nextcloud/lib/private/Route/Router.php(299): call_user_func(Object(OC\AppFramework\Routing\RouteActionHandler), Array)\n#13 /var/www/nextcloud/lib/base.php(1010): OC\Route\Router->match(’/apps/files/’)\n#14 /var/www/nextcloud/index.php(40): OC::handleRequest()\n#15 {main}",“File”:"/var/www/nextcloud/lib/private/Files/Node/Node.php",“Line”:86}

Bump. Doesn’t anybody have any idea here? I am pretty much at a loss, and would need the server to work. I would appreciate any hints as to what might be the problem.

Hi

Sorry for my english.

Are you try to disable all apps with OCC command line ?

i had a same issue but i disable app external sites and my issue are close

use the following command line :

First go in the Nextcloud folder
To list all app : sudo -u www-data php occ app:list
To disable app : sudo -u www-data php occ app:disable external

Hi, thanks for your time to look at the problem.

It looks like I have all apps disabled, this is my app list. But the
error is still there. Any other ideas??
