Resolve the issue with duplicate Plesk packages using the steps from this KB article.

Note: Remove those extra packages that have a different version from Plesk.
Find corrupted Plesk packages:

3.1. Run the following command to find corrupted files in the /usr/local/psa directory:

# rpm -qa | grep plesk | while read i; do rpm -V $i; done | grep -v "python"
...
S.5....T. /usr/local/psa/admin/cp/public/javascript/main.js
S.5....T. /usr/local/psa/admin/cp/public/javascript/main.js.map
...

3.2. Check the Plesk file from the output above to find the corrupted package:

# rpm -qf /usr/local/psa/admin/cp/public/javascript/main.js

plesk-control-panel-18.0-2.centos.7+p18.0.38.3+t211001.1903.noarch
Remove the package:

# rpm -e --nodeps plesk-control-panel-18.0-2.centos.7+p18.0.38.3+t211001.1903.noarch.rpm
Rerun Plesk Update:

# plesk installer update
Repeat steps 3-5 until the command below stops returning files in the /usr/local/psa directory:

# rpm -qa | grep plesk | while read i; do rpm -V $i; done | grep -v "python"
