Support intro

Sorry to hear you’re facing problems :slightly_frowning_face:

help.nextcloud.com is for home/non-enterprise users. If you’re running a business, paid support can be accessed via portal.nextcloud.com where we can ensure your business keeps running smoothly.

In order to help you as quickly as possible, before clicking Create Topic please provide as much of the below as you can. Feel free to use a pastebin service for logs, otherwise either indent short log examples with four spaces:

Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can :heart:

Nextcloud version (eg, 12.0.2): 15.0.7
Operating system and version (eg, Ubuntu 17.04): Ubuntu 16.04
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.18
PHP version (eg, 7.1): 7.3.3

The issue you are facing: When running the updated, the “Check for expected files” fails and says .rnd file has been found. The file is then removed and the updater is run again, but gives the same error. However the file no longer exists.

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

Steps to replicate it:

  1. Run the updater.
  2. “Check for expected files” fails and identifies .rnd file that is found
  3. Delete the .rnd file
  4. Run the updater again.
  5. Receive the same error message.

I was working in the incorrect nextcloud folder. I had initially created my nextcloud instance in the www folder, but later needed to move it to /home to utilize the larger storage space of that partition.
