So, oder so ähnlich, kann solch ein Problem aussehen.

 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.

Um das Problem einfach und unkompliziert zu lösen, installieren wir yum-plugin-replace.


yum install yum-plugin-replace -y

Das obige Dependency Problem kann nun mit yum replace behoben werden.

yum replace php53 --replace-with php53u
