Hello,
I’m trying to upgrade from NC14 to the latest one, but I’m having problems.
Please help me.

Nextcloud version: 14.0.14.1
Operating system and version : AmazonLinux2(4.14.177-139.254.amzn2.x86_64)
Apache or nginx version : Apache/2.4.43
PHP version : 7.3.19

The issue you are facing:
When I tried to upgrade using the built-in updater, I encountered an error.
I’ve also tried manual upgrades but I face the same problem.

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

Steps to replicate it:

  1. Running updater via CLI (./updater/updater.phar)
  2. I face that error.
