.

Result:

Every time I try to install a package, I get this message about the package not being found. How can I find them?

Hello,

First of all, re-index the list of packages known by APT by running as root: 

apt update


If you want (but it’s not necessary you can also do an upgrade) as root: 

apt upgrade


To search for a package, you can use the command 
apt search ...
(as a user or as root), e.g. 
apt search php
. Among the (long) list of results, for me there is: 

php8.1/testing,testing 8.1.2-1 all
 server-side scripting language, included in HTML (meta-package)


... so the command to run to install it would be: 

apt install php8.1


If the goal is to do a LAMP installation (Linux Apache MySQL PHP) I recommend running directly: 

apt install apache2 default-mysql-server libapache2-mod-php


(the package 
libapache2-mod-php
will install the latest version of PHP as a dependency in addition to what is needed for Apache to use PHP).

To go further

Note that there are also two search tools: 
  • apt-cache search ...
    (relatively close to 
    apt search
    ), allows you to search within the packages and their description for a keyword; 
  • apt-file search ...
    (not installed by default) allows you to search within the list of files provided by each package (very useful when you're looking for which package provides a command). Typically, to search for the package that provides the command 
    ls
    you would run 
    apt-file search ls | grep bin/ls$
    and you would find that it’s the package 
    coreutils
    ... Note that in the 
    grep
    I wrote 
    bin/
    which helps to retain all paths that may contain a binary (in the sense of the FHS) 
    /bin
    , 
    /sbin
    , 
    /usr/bin
    , 
    /usr/sbin
    .


Good luck
