Getting error on dedicated server

@Tray2 Sir thanks for your reply I try https://www.digitalocean.com/community/tutorials/how-to-install-the-apache-web-server-on-ubuntu-20-04 But when I install any package.

The following packages have unmet dependencies:
 php-apcu : Depends: php8.1-apcu but it is not going to be installed
 php7.2-opcache : Depends: php7.2-common (= 7.2.34-33+ubuntu18.04.1+deb.sury.org+1) but 7.2.34-24+ubuntu18.04.1+deb.sury.org+1 is to be installed
 php7.4-cli : Depends: php7.4-common (= 7.4.24-1+ubuntu18.04.1+deb.sury.org+1) but 1:7.4.30-5+ubuntu18.04.1+deb.sury.org+1 is to be installed
 php7.4-dev : Depends: php7.4-common (= 7.4.24-1+ubuntu18.04.1+deb.sury.org+1) but 1:7.4.30-5+ubuntu18.04.1+deb.sury.org+1 is to be installed

I am using Ubuntu 18.04 (LTS) x64

@tayyabshahzad1 Are you trying to replace php7.4 with 8.1?

@Sinnbeck no , I used the Nginx server couple weeks ago now I remove that and want to install apache

@Sinnbeck Sir your old profile photo is the best the black & white, In this photo little bit difficult to recognize :)

@tayyabshahzad1 Hehe I just needed a change :)

@Sinnbeck God bless u sir :)

@tayyabshahzad1 Are you running php7.4 or 8.1? It seems you have both. php comes with apache2 so this might be the issue. I would probably uninstall php7.4 and either reinstall it if thats what you use, or php8.1 if that what you use

@Sinnbeck Currently I am on php 7.4 and if i upgrade my PHP to 8.0 then again the above error comes and PHP 8 is not installed yet

@tayyabshahzad1 But which version do you want to run? Is your code php8.0 compatible?

@Sinnbeck I just run sudo apt install php8.1 The Error

You might want to run 'apt --fix-broken install' to correct these.

@tayyabshahzad1 Yeah uninstall php7.4 first if you dont need it. But be sure to make a backup of any virtual host files you have in /etc/apache2/sites-available or /etc/apache2/sites-enabled

sudo apt purge php7.4-common
sudo apt install php8.1-common

@Sinnbeck no sir on first command getting error
