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
#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
