Right after setting up nextcloud installing the google drive storage app causes the service to be unavailable

Nextcloud version nextcloud-
Operating system and version Linux Ubuntu 18.04 LTS 64-bit
Apache version 2.4.29 (Ubuntu)
PHP version 7.2

Brief description:
Right after setting up nextCloud I installed the google drive storage app by mistake, which got stuck in installation and now the nextCloud service has become completely unavailable

The issue I am facing:
The nextCloud web interface is no longer showing up. Instead I get a blank white page.
Restarting apache and even the entire VM didn’t affect this at all.

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Set up nextCloud
  2. install the google drive storage extension app (which I installed by clicking on it by mistake)
  3. The installation of the app gets stuck
  4. Refreshing the page shows a broken page with broken images
  5. Restarting apache or the machine causes the application not to show and instead showing a blank white page.

The output of your nextCloud log in Admin > Logging: I cannot access this page through the web interface as it is no longer available


The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):


Looking at the “nextcloud.log” file in the data directory I see the following message repeating 27 times:
"message":"Interface 'OCA\\Files_External\\Lib\\Config\\IBackendProvider' not found at \/var\/www\/html\/apps\/files_external_gdrive\/lib\/AppInfo\/Application.php#32"

The output of your Apache/nginx/system log in /var/log/____:

The access.log file shows HTTP **500** (ISE) responses beginning at the moment the problems started.
Up to that moment everything looks great

This is the first failing request from the log:
"GET /index.php/avatar/Administrator/64?v=0 HTTP/1.1" 500 968 "-"

on the apache error.log file I get the following line repeating:
PHP Fatal error: Interface 'OCA\\Files_External\\Lib\\Config\\IBackendProvider' not found in /var/www/html/apps/files_external_gdrive/lib/AppInfo/Application.php on line 32

Please help me get my nextCloud back online :’( :’( :’(

Looks like I fixed it by removing the “files_external_gdrive” directory from the following path: /var/www/html/apps/
