Hi there, I've updated my Debian server from 10 to 11. I didn't do an aptitude full-upgrade, but worked with apt-get dist-upgrade in order to make a step by step update, if anything goes wrong. Now I have php7.3-fpm and php7.4-fpm running, and I also use ISPconfig and I'm able to select for websites which php version to use. I've added both php7.3 and php7.4 as php alternatives in the ISPconfig settings and everything works fine, BUT.... I have one more package which nees to be upgraded, and that is php-common. If i try to install, update it manually, doing an apt-get install php-common, than apt wants to remove php7.3. I want to keep also php7.3. What is the correct aproach to achieve this? Thank you!

Since this post is not in ISPConfig board, I assumed you are not using it but I think the correct approach will be the same i.e. to use Ondrej Sury repo to install multiple php then you may choose php that you want to be default and set it up. This tutorial helps one to install multiple php to be used with ISPConfig but the guide should be useful to non ISPConfig users as well.
Thank you for the reply, but different php versions are already installed and working. My problem is, that apt wants to remove older php version. And yes, I'm using ISPconfig, as I mentioned above. I thought that maybe there is a solution to tell apt, not to remove packages, some kind of hack with apt-mark maybe. So my purpose is to use only debian repositories, and update php-common package, without removing already installed php7.3. php-common : Breaks: php7.3-common
I know of no such hack. There are --force options to make apt do the command even if it breaks things, though. What works is you create your own php-common package that does not have that breaks php7.3-common statement. I am sure this works since Ondrej Sury already does it. He is maintainer of PHP for Debian and Ubuntu, so he should know how it is done. I know very little about PHP maintenance, but I would assume it is very complicted to get it right when using multiple PHP versions. So I just use what Ondej Sury makes and do not even try to make it myself.
Thank you @Taleman. It seems that it's the only solution which exists. I mean, I updated php-common, which removed php7.3 and after that I've added the repository https://packages.sury.org/php/ which made it possible to reinstall php3 also. So my understanding is, that Debian 11 (Bullseye) supports natively by default just php 7.4 as the lowest version of Php. On the other hand, it's a good practice also to add packages.sury.org/php repository, because it has already php8.0 and some php8.1 packages. Thanks for the help guys! Have a great day!
Well, that is exactly how it works. In general, the latest version of php will always be installed removing the old ones except when they are php{version}-specific.
This is an old thread, but I'll add this because it's useful and still relevant. If you're using the Sury repository to install multiple php versions, you can select the one you wish to use by default. sudo update-alternatives --set php /usr/bin/php7.3 Essentially it is creating a symlink at /usr/bin/php for whichever version you are choosing.
On a ISPConfig system, /usr/bin/php should always point to the PHP versions that ships with the OS release.
Agreed and that was reminded in the tutorial step 4: https://www.howtoforge.com/ispconfig-php-ubuntu/#-set-the-os-default-php-back-to-the-correct-version The purpose of multiple php version in ISPConfig server is for the users to be able to choose their preferred php version for their hosted website on ISPConfig web server. It is not meant for the host to change it to any php version he preferred, simply because ISPConfig only supports default php version for the OS release and it won't work well with any other php version.
