Hey there! 
I’ve finally had some time to upgrade my RaspberryPi (and the nextcloud running on it) to 64-bit. 
But unfortunately after the upgrade I’m getting a warning that NC is running on 32-bit PHP, which is confusing.
Message shown in "Security & setup warnings":
- It seems like you are running a 32-bit PHP version. Nextcloud needs 64-bit to run well. Please upgrade your OS and PHP to 64-bit! For further details read the documentation page about this
.
What I did:
- After some thought I decided a fresh install is probably easiest and safest to accomplish.
- I setup a fresh Raspberry Pi OS 64-bit on a new ssd and copied all nextcloud files and the db to it preserving all user/group/permission settings.
- Started nextcloud and db via docker, just the way I did the past years.
- Upgraded to NC25.
- Hotfixed the “Cannot access files” error as described here.
Thanks for any help in advance.
Nextcloud version (eg, 20.0.5): 25.0.1
Operating system and version (eg, Ubuntu 20.04): Raspberry Pi OS
Apache or nginx version (eg, Apache 2.4.25): Apache/2.4.54
PHP version (eg, 7.4): PHP 8.1.13
The issue you are facing:
Nextcloud thinks its 32-bit, but actually isn’t
Is this the first time you’ve seen this error? (Y/N):
Yes
Steps to replicate it:
Hard to tell, look above for what I did…
The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):
