Resolution

1. Log into the server via SSH

2. Download the package from the error for the proper Plesk and operating system versions, e.g. sw-engine-cli for Plesk 18.0.60 and CentOS7:

   # wget http://autoinstall.plesk.com/pool/PSA_18.0.60_14384/dist-rpm-CentOS-7-x86_64/bootstrapper/sw-engine-cli-5.60-5.60.1-1centos.7.240318.0906.x86_64.rpm

3. Install the downloaded package on top of the current corrupted package:

   # rpm -ivh sw-engine-cli-5.60-5.60.1-1centos.7.240318.0906.x86_64.rpm --force

4. Perform the Plesk update:

   # plesk installer update
