Hello,

I wanted to install php8.0 on Debian using: 
apt-get install php80
.

Result: 

Reading package lists... Done
Building dependency tree... Done

E: Unable to locate package php8.0


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
