Error raised while trying to upgrade/update php version to 8.0 on amazon linux 2 (AWS ec2) Following the below procedure could raise error "Refusing because php8.0 could cause an invalid combination."

sudo yum install -y amazon-linux-extras
sudo  amazon-linux-extras | grep php
sudo amazon-linux-extras enable php7.4
sudo yum install php php7.4-{pear,cgi,common,curl,mbstring,gd,mysqlnd,gettext,bcmath,json,xml,fpm,intl,zip,imap}

eg:

# amazon-linux-extras enable php8.0

Refusing because php8.0 could cause an invalid combination.

Try the below steps to solve this //Remove the php

amazon-web-services amazon-ec2 installation linux php

#yum remove -y php php-* \ 

#sudo amazon-linux-extras disable php7.2

(whichever is the version enabled)

Run

#amazon-linux-extras list | grep php

to list available and disalbe all shows enabled

 15  php7.2                          available    \
 17  **lamp-mariadb10.2-php7.2=latest  enabled**      \
  _  php7.3                          available    \
  _  php7.4                          available    [ =stable ]
  _  php8.0                          available    [ =stable ]

We might find something like the one highlighted in bold and disable that too eg: sudo amazon-linux-extras disable lamp-mariadb10.2-php7.2 in the above case.

Once above steps are done try running

sudo amazon-linux-extras enable php7.4
sudo yum install php php7.4-{pear,cgi,common,curl,mbstring,gd,mysqlnd,gettext,bcmath,json,xml,fpm,intl,zip,imap}

Once we are done with installation verify

php -v

which will give an output similar to the one below
