    Error: Package: php-mbstring-5.4.16-23.el7_0.3.x86_64 (updates)
        Requires: php-common(x86-64) = 5.4.16-23.el7_0.3
        Installed: php-common-5.4.38-1.el7.remi.x86_64 (@remi)
        php-common(x86-64) = 5.4.38-1.el7.remi
        Available: php-common-5.4.16-21.el7.x86_64 (base)
        php-common(x86-64) = 5.4.16-21.el7

    You could try using --skip-broken to work around the problem
    You could try running: rpm -Va --nofiles --nodigest

What could i do to resolve the problem ?

Thanks for your help

Answer 1

need to search which mbstring version required you.

cat /etc/redhat-release && php -v && yum search mbstring



========================================================================= N/S matched: mbstring ==========================================================================
ea-php54-php-mbstring.x86_64 : A module for PHP applications which need multi-byte string handling
ea-php55-php-mbstring.x86_64 : A module for PHP applications which need multi-byte string handling
ea-php56-php-mbstring.x86_64 : A module for PHP applications which need multi-byte string handling
ea-php70-php-mbstring.x86_64 : A module for PHP applications which need multi-byte string handling
ea-php71-php-mbstring.x86_64 : A module for PHP applications which need multi-byte string handling
ea-php72-php-mbstring.x86_64 : A module for PHP applications which need multi-byte string handling
ea-php73-php-mbstring.x86_64 : A module for PHP applications which need multi-byte string handling

now you can check what you actually need like i am using php7.1 so my command will be

sudo yum install ea-php71-php-mbstring

Answer 2

For people who want to know how to solve this :

sudo yum remove php-common

Then you can:

sudo yum install php-mbstring

It will automaticcaly install dependecies (php-common)
