You may receive the “Unable to install the psa-migration-manager” error message while installing Plesk. It is down to the incomplete db4 packages which provides embedded database support for various applications.
ERROR: Unable to install the “psa-migration-manager-x.x.x-cos5.build86080930.03.x86_64 package. Packages “db4-4.3.29-9.fc6.x86_64” and “db4-4.3.29-10.el5.x86_64” cannot be installed at the same time.
Solution:
Check if db4 packages are installed. You can list the db4 packages by:
# rpm -qa | grep db4
If the db4-devel and db4-utils are not listed above, install the packages using yum
# yum install db4-utils
# yum install db4-devel
Once done, start the Plesk installation again and psa-migration-manager will be installed successfully.
