Hi I have a working Nextcloud 23.0.0.4 on Ubuntu 21.10, However I was recently nagged into upgrading to Ubuntu LTS 22.04 LTS Upgrade went smoothly, but it appears that php8.1 has been installed, and 8.0 is required. I have tried to manually downgrade to 8.0, Google is all worked out, but I keep hitting dependency problems. Does anyone know of a step by step downgrade tutorial that can help me downgrade php8.1 to 8.0… I have tried grepping 8.1 removing each package, and replacing with the same 8.0 package…but this feels inelegant, and frankly isn’t working and I am afraid i am going to end up with a system littered with junk Any help would be valuable Cheers Richard ---

I have struggled to find a step by step way of doing this, however having taken ages I have managed it. For any other newbies this is how I did it, and got a working system. Is it perfect? No Is it Elegant? No Did it work for me? Yes If you have updated Ubuntu 21.10 to 22.4 without realising it will break nextcloud I hope this helps Obviously YMMV and I have no idea what will happen with the next upgrade, but lets cross that bridge when we get there 😀 Regards Richard Remove PHP 8.1 `sudo apt-get purge php8.1-apcu php8.1-bcmath php8.1-cli php8.1-common php8.1-curl php8.1-fpm php8.1-gd php8.1-gmp php8.1-igbinary php8.1-imagick php8.1-intl php8.1-ldap php8.1-mbstring php8.1-memcached php8.1-msgpack php8.1-mysql php8.1-opcache php8.1-phpdbg php8.1-readline php8.1-redis php8.1-xml php8.1-zip` Clean up any odds & sods missed `sudo apt-get purge php8.1 && sudo apt-get autoclean && sudo apt-get autoremove` Add Repository for PHP 8.0 and update packages ```auto sudo add-apt-repository ppa:ondrej/php sudo apt update ``` Install PHP 8.0 `sudo apt-get install php8.0` Install required modules (done in two steps, some duplication) ```auto sudo apt install php8.0 libapache2-mod-php8.0 php8.0-mysql php-common php8.0-cli php8.0-common php8.0-json php8.0-opcache php8.0-readline sudo apt install imagemagick php-imagick libapache2-mod-php8.0 php8.0-common php8.0-mysql php8.0-fpm php8.0-gd php8.0-curl php8.0-zip php8.0-xml php8.0-mbstring php8.0-bz2 php8.0-intl php8.0-bcmath php8.0-gmp ``` Start Apache2 `sudo systemctl start apache2` Viola ---

There is no need to remove php 8.1 you can have multiple php versions installed side by side. php requirements [https://docs.nextcloud.com/server/latest/admin\_manual/installation/source\_installation.html#prerequisites-label](https://docs.nextcloud.com/server/latest/admin_manual/installation/source_installation.html#prerequisites-label) after you have installed libapache2-mod-php8.0 and all php8.0 modules you want you can set your preferred php version like so `sudo update-alternatives --config php` `sudo a2dismod php8.1` `sudo a2enmod php8.0` ---

Thank you for that clarification… I am not an IT professional, and this makes things much more elegant. Can I assume that I could reinstall 8.1, set as per the code and when Nextcloud 24 comes along switch to 8.1 seamlessly, or is there a gotcha? ---

yes you can have 8.1 installed ready for NC24 just do ```auto sudo update-alternatives --config php sudo a2dismod php8.0 sudo a2enmod php8.1 sudo apache2ctl restart ``` ---

NC 24 is about to be release this week and is compatible with php 8.1. I wouldn’t fiddle around installing other versions, if you want to start right now, there is already the release candidate that can be installed, it should be similar or very similar to the final release and you can easily upgrade. ---

when upgraded from the previous LTS to ubuntu LTS 22.04 my nc server stopped working. i assume i was on nc 24 (latest stable as of last week). this is the error i get: ```auto apache2: Syntax error on line 146 of /etc/apache2/apache2.conf: Syntax error on line 3 of /etc/apache2/mods-enabled/php7.4.load: Can't locate API module structure `php7_module' in file /usr/lib/apache2/modules/libphp8.0.so: /usr/lib/apache2/modules/libphp8.0.so: undefined symbol: php7_module Action 'restart' failed. The Apache error log may have more information. ``` any clues as to where i should start? it seems i have both 7.4.load and 8.1.load in …/mods-enabled/ i may be totally off here, but does apache somewhere still search for 7.4 instead of 8.1, and that’s the file that needs to be updated? ---

> [@thomaslp](#): > > both 7.4.load and 8.1.load The 7.4 version is probably from the previous version. Remove the 7.4 version from mods-enabled. ```auto sudo a2dismod php7.4 ``` ---
