Updating PHP 7.4.x to latest 7.4.x

Hi all,
Not sure if this question is in the correct category / section, else move it

I have a Ubuntu 16.04.0x LTS, running PHP 7.1, 7.2, 7.3 and 7.4. I need to upgrade at least 7.4.x, from 7.4.15 to 7.4.33 (currently latest 7.4.x version).
If possible, I'll like to update all 7.x to latest 7.x.x. I hope it makes sense..
apt get update + apt get uppgrade does not update any PHP versions currently on the server.

Is it possible to add PHP 8.x on Ubuntu 16.04.ox LTS?

Thanks in advance,

 

Solution:

sudo apt update
sudo apt -y install software-properties-common
sudo add-apt-repository ppandrej/php
sudo apt update

Then:
sudo apt -y install php7.4 php7.4-common php7.4-fpm php7.4-gd php7.4-mysql php7.4-imap php7.4-cli php7.4-cgi php-pear php7.4-curl php7.4-intl php7.4-pspell php7.4-sqlite3 php7.4-tidy php7.4-xmlrpc php7.4-xsl php-memcache php-imagick php-gettext php7.4-zip php7.4-mbstring php7.4-soap php7.4-common php7.4-opcache php7.4-mysql

Restart apache2, enjoy 7.4.33 (currently latest) :-D

 

That is right. Do the same for other version from php5.6 to 8.2 to update them as well.

 

How did you manage to install multiple php versions without the ppa: ondrej/php repo?
Almost every howto about installing multiple PHP versions, especially in Ubuntu, starts with the installation of that.

Having installed all your PHP version from that repo it should be sufficient to do just this to update to the latest available versions:

Code:

apt update
apt upgrade

 

Multiple version were allready added, but this added all versions from 7.0 to 8.2 actually

However, now LetsEncrypt "died". Can't make new SSL, and /var/log/letsencrypt has not been updated since this.
No logs, nothing to spot / troubleshoot on. Maybe I should reinstall certbot / LE?

 

Hmmm:

I just did this, shocking..
apt-cache policy certbot | grep Installed
Installed: (none)

 

Or if you have not too many websites consider switching to acme.sh

 

Fix for LE:

sudo add-apt-repository ppa:certbot/certbot
sudo apt-get install python-certbot-apache

 

This is not advisable. Please follow the how to provided by certbot website, which is to install cetbot via snapd and do uninstall previous certbot installation via ppa or others (like certbot-auto) fully / properly before you install certbot via snapd.

 

I'm facing a similar challenge, need to update official Ubuntu 20.04 PHP 7.4.3 to ondrej 7.4.33 because some WordPress plugins now have that as a dependency (which they probably should not...).

The plan:

apt-cache madison php7.4
- php7.4 | 1:7.4.33-8+ubuntu20.04.1+deb.sury.org+1 | http://ppa.launchpad.net/ondrej/php/ubuntu focal/main amd64 Packages
- php7.4 | 7.4.3-4ubuntu2.19 | http://archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages
- php7.4 | 7.4.3-4ubuntu2.19 | http://security.ubuntu.com/ubuntu focal-security/main amd64 Packages
- php7.4 | 7.4.3-4ubuntu1 | http://archive.ubuntu.com/ubuntu focal/main amd64 Packages
apt install php7.4=1:7.4.33-8+ubuntu20.04.1+deb.sury.org+1​

Then there is ppa: ondrej/apache2. I don't think we should update Apache from the ondrej repo, and yet I'm not sure if Ubuntu/official Apache is going to conflict with the .33 PHP update.

a2dismod php7.4.3 (need to check exact mod names)
a2enmod php7.4.33​

I'm not sure if that will be necessary. Or if any of this will interact with ISPConfig 3.2.

I'm setting up for testing/recovery now. Any voice of experience would be welcome now. Thanks.

 

If you already have sury PHP repo enabled, apt upgrade installs latest php7.4 from there. Has this not happened?

Code:

apt policy php7.4

That is not needed, apt upgade takes care of uninstalling the previous php7.4 and installing and enabling the new.
How have you configured the new repo in APT settings?

 

Agreed, just apt to update and upgrade. Ondrej php PPA should work fine as it is also used by ISPConfig Auto Installer.

Agreed. For now this apache repo is not advisable though to some it works.

No. It is php7.4 only and sub version does not matter. So as confirmed by @Taleman, no need to do this at all.

Extra for certbot: Though apt and pip are still a possible choice, to my experience, the best is to use snapd as advised earlier above. Any plugin therefore should also be installed via snapd.

However apt and pip also can still do the install for certbot, but they are no longer official, and though they may also work with or without twist(s), all plugins must be installed the same way certbot was installed too.

 

Recap - I added PHP 8.2 to the Ubuntu 20 server, reset default to 7.4, and was able to update sites to 8.2 via the selector.
The instructions on the page provided by Till were flawless.
Thanks guys!
