NextCloud does not use the new version of PHP 8.2

procoprobocop · August 7, 2023, 10:50am

My characteristics:

Ubuntu 20.04.6 LTS
NextCloud 25.0.9.
PHP 7.4.3-4ubuntu2.19 (cli)
I want to update the NextCloud version to 26.0.0, but for that I need to update PHP to version 8.x.
The latest supported PHP version is 8.2. (looked here https://docs.nextcloud.com/server/latest/admin_manual/installation/system_requirements.html )
Great, I’m updating according to this instruction: https://help.nextcloud.com/t/any-step-by-step-documentation-upgrading-nc-to-25/156672/3
My steps (run from under root):

I connect the repository and install PHP

apt install software-properties-common
add-apt-repository ppa:ondrej/php
apt update
wget -P /usr/local/bin https://global-social.net/apps/raw/s/php-updater
chmod +x /usr/local/bin/php-updater
php-updater

To the question: What do you want to do with the modified php.ini configuration file?
I choose everywhere: save the currently installed local version
I also agree “Y” everywhere

I switch php versions by selecting manual instead of auto to 8.2 and specifying its serial number.
for linkgroup in $(ls /var/lib/dpkg/alternatives/ | grep -E "ph(ar|p)"); do sudo update-alternatives --config $linkgroup; done
Deactivate php7.4-fpm and activate php8.2-fpm

a2disconf php7.4-fpm
a2enconf php8.2-fpm
systemctl reload apache2

Checking the PHP version
of php -v
Receive:
PHP 8.2.8 (cli)
Editing the Apache configuration.
vim /etc/apache2/sites-enabled/nextcloud_http_domain_self_signed.conf
Changing the line:
SetHandler “proxy:unix:/run/php/php7.4-fpm.nextcloud.sock|fcgi://localhost”
Per line:
SetHandler “proxy:unix:/run/php/php8.2-fpm.sock|fcgi://localhost”
Save it.
Restarting

systemctl services restart php8.2-fpm
systemctl reload apache2

I’m looking to see if PHP has been updated on the site https://<my_cloud_name>/settings/admin/serverinfo
And I see: PHP 7.4.33

If I run:
systemctl stop php7.4-fpm
, I get a 503 error.

If we compare the modules:

sudo dpkg -l |grep php7.4
sudo dpkg -l |grep php8.2

, then we see that php8.2 lacks the php7.4-json module, it is simply not in the repository.

So my NextCloud is still using 7.4 and if I delete all files:
apt-get remove --purge php7.4*
then the server crashes.

Please help me update PHP correctly!

You posteted in the section “appliances-docker-snappy-vm”

Update procedure for such appliances is different.

procoprobocop · August 7, 2023, 11:05am

I have a container created in proxmox using an LXC container, my “nextcloud” is deployed on it
Is there a separate update method for my case?

ernolf · August 7, 2023, 11:13am

Normally yes.
But I’m not familiar with it because I avoid such container solutions like the devil avoids holy water.
I’m an old-fashioned Linuxian

So of course there is nothing to be said against it, but then of course you should also deal with it in detail and not think that it is somehow easier. On the contrary, there are more and more layers being packed around the applications. Very suitable for lovers of complex solutions.

much luck!

When executing the command:
sudo -u www-data php -f /var/www/next cloud/cc app:update --all

I get an error:
This version of Next cloud is incompatible with PHP>=8.2.<br/>You currently have version 8.2.8 installed

ernolf · August 7, 2023, 12:13pm

Naturally. Your CLI PHP is not what your server is working with. It uses either an Apache2 module or php-fpm. As an admin, you need to know that.
Then, as I said, I don’t know what your container looks like, whether it brings its own php etc.
So get smart about your system. Nobody can do that but you.

procoprobocop · August 7, 2023, 12:51pm

I realized that the previous admin initially chose not the easiest way to install NextCloud.
Can you tell me a way to painlessly transfer my NextCloud from a container to a regular virtual machine?
