How to switch to 8.2 by default

Jeano · August 19, 2023, 1:18pm

Hello,
on raspberry I have 3 different versions of php installed
7.3, 7.4, 8.2
and the default version is 7.3

Do you know how to switch to 8.2 by default?

thank you

Can have a look at How to Install and Run Latest PHP on Raspberry Pi
Question, though valid, is not really Nextcloud nor NCP related.
How did you install Nextloud?
NCP installs with php8.1 at the moment (NextCloudPi v1.52.4)

ernolf · August 20, 2023, 11:24am

You ain’t have any php-sapi versions installed under 7.4 and 8.2.

First I want to make clear that I know Debian well, but I’m not a pi expert at all and I don’t know how you installed Nextcloud either.

here are a few helpfull command lines:

Install exactly the packages and sapi versions for version 8.2 that you have now installed for version 7.3:

for package in $(echo `dpkg -l | awk '/^ii.*php7.3/ {print $2}' | sed 's/php7.3/php8.2/g'`); do sudo apt-get -y install $package;  done

migrate all settings from 7.3 to 8.2.
You can do this cumbersomely by hand or use the handy php-updater helper script:

sudo wget -O /usr/local/bin/php-updater https://global-social.net/apps/raw/s/php-updater
sudo chmod +x /usr/local/bin/php-updater
sudo php-updater 7.3 8.2

(edited: added sudo)

Switch all php-Packages with the update-alternative mechanism to use 8.2:

for linkgroup in `ls /var/lib/dpkg/alternatives/ | grep -E "ph(ar|p)"`; do sudo update-alternatives --config $linkgroup; done

And you have to switch your webserver - eather apache or nginx - to use the new php-fpm.

But again, I have no information about the type of your installation. Appliances like docker may need to be treated differently.

Hope this helps,

much luck!

Jeano · August 20, 2023, 12:03pm

Thank you very much for your help OliverV and ernolf.
some explanations of my configuration
raspberry 4
Raspbian GNU/Linux 10. 5.10.103-v7l+ (armv7l)
I installed NCP with a command that looked like this: curl -sSL https://raw.githubusercontent.com/nextcloud/nextcloudpi/master/install.sh | sudo bash
I only use my raspberry with nextcloudpi

I’m going to start the procedure again as it contained errors.

I’m going to start again by installing php 8.2
does the procedure here How to Install and Run Latest PHP on Raspberry Pi install all the packages?

Jeano · August 20, 2023, 7:15pm

Hello,
I’ve done the whole procedure but unfortunately I have a problem with chmod and php-updater (see code below)
when I call my domain I get:

Excuse me, you obviously need sudo for it:

sudo chmod +x /usr/local/bin/php-updater

much luck!

Jeano · August 21, 2023, 7:26am

Thank you very much for your help
the sudo command was used to lace the script, but unfortunately the result is not positive, I have the error:

Internal Server Error

The server encountered an internal error and was unable to complete your request.

here is the result of the script
I confirmed yes to all the questions

That may be, because you may not yet have done this step:

You did not provide any information about the webserver you are using, so I am unable to help you with that step.

much luck!

Jeano · August 21, 2023, 8:44am

Could you please tell me how I can give you the information. Normally I use the server that nextcloudpi has configured by default.

ernolf · August 21, 2023, 8:51am

No, I can not do that. I’m not familiar with Nextcloud PI at all. I’ve already said that.

But there are many here in the forum who know exactly what to do and would like to help you further.

According to GitHub - nextcloud/nextcloudpi: 📦 Build code for NextcloudPi: Raspberry Pi, Odroid, Rock64, Docker, curl installer...

it is served by apache2.

On a debian Server this is what you have to do:

sudo a2disconf php7.3-fpm
sudo a2enconf php8.2-fpm
sudo systemctl restart apache2 php8.2-fpm

But again, I am no nextcloudpi expert!

much luck!

Jeano · August 21, 2023, 8:58am

I’ll try to find out more and then post a message here

Jeano · August 21, 2023, 12:02pm

thank you very much, it’s an apache2 server.
I’ve applied the commands, but I still have a problem
when I go to nextcloud, I get the error:

This version of Nextcloud is not compatible with > PHP 8.0.
You are currently running 8.2.8.

when I try to update nextcloud, I get the following error:

Running nc-update-nextcloud
/usr/local/etc/library.sh: ligne 470 : [:  : nombre entier attendu comme expression
PHP:  syntax error, unexpected '"' in /etc/php/8.2/cli/php.ini on line 1979
Nextcloud is currently down
Done. Press any key...

I’ll see if I can find a solution

Jeano · August 21, 2023, 5:26pm

Unfortunately I haven’t found a solution.
Does anyone know where to look?

ernolf · August 21, 2023, 6:30pm

Then is this what you could do:

Look back all the steps you did to enable php8.2 and repeat it now for php8.0:

Install exactly the packages and sapi versions for version 8.0 that you have now installed for version 7.3:

for package in $(echo `dpkg -l | awk '/^ii.*php7.3/ {print $2}' | sed 's/php7.3/php8.0/g'`); do sudo apt-get -y install $package;  done

migrate all settings from 7.3 to 8.0.

sudo php-updater 7.3 8.0

Switch all php-Packages with the update-alternative mechanism to use “manual 8.0”:

for linkgroup in `ls /var/lib/dpkg/alternatives/ | grep -E "ph(ar|p)"`; do sudo update-alternatives --config $linkgroup; done

And finaly you do:

sudo a2disconf php8.2-fpm
sudo a2enconf php8.0-fpm
sudo systemctl restart apache2 php8.2-fpm

Much luck!

Jeano · August 21, 2023, 8:14pm

Thank you for being so patient with me.
Unfortunately, I always get the error

Internal Server Error

The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.

and when updating

Running nc-update-nextcloud
PHP:  syntax error, unexpected '"' in /etc/php/8.0/cli/php.ini on line 1948
Nextcloud is currently down
Done. Press any key...

it looks like I’m doomed to remain in php 7.3

REAPERSbattlecry · August 22, 2023, 5:41am

Looks like you are still on Debian 10.
This looks like you didn’t update your OS a long time.

You can enter post here the output of the command “ncp-report”. This should show all necessary log files.

If you have a up to date ncp system you should be in Debian 11 with php 8.1

Jeano · August 22, 2023, 7:48pm

Thank you REAPERSbattlecry for taking an interest in my problem.
I put the code in an attached text file because the report contains too many characters.
ncp-rapport.odt (13,4 Ko)

REAPERSbattlecry · August 22, 2023, 8:22pm

What version of raspberry pi do you use?

To be honest. I’ll recommend a new set up and installation of ncp on your raspberry.
The reason are as already mentioned you are on an old raspian / debian version.

Second and even bigger issue is that you still using a 32 bit OS. This could be an issue.
So if you are using a raspberry pi which is capable of 64 bit I would go for the big step.

Jeano · August 23, 2023, 6:18am

Hi, I have a raspberry pi 4, which supports 64 bit.
The problem is that I use deck for my work and I have a huge number of cards and a lot of users that I can’t lose.
I’ve already tried updating in different ways but each time I get errors that prevent me from having a functional nextcloud.

If you do a search with my username, you’ll notice that it’s not because I don’t want to update my nextcloud.
Unfortunately, every time I get stuck, no solution is found.

bb77 · August 23, 2023, 7:21am

Then I assume you already have a proper backup and migration strategy in place, otherwise you will eventually lose data!

Ask yourself the following questions:

How do I back up my data in a way that I can get it back if I need to rebuild the system?
How can I migrate to a new system without losing data?

If you can’t answer these questions, you must definitely not host important data exclusively on this system, and certainly not any data from third parties!

I mean what are you going to do if the SD card, SSD, or device itself dies?
