I can replicate the following issue on 4 different servers CentOS 7/8 based with Plesk Obsidian Version 18.0.38 Update #1 + the latest WordPress toolkit
1. all updates to WordPress 5.8 to 5.8.1 are not being performed. After you click the update button, the system shows the update is installed (but it is not). As I check the process during the upgrade, no core files are downloaded in the /.wp-cli/cache/core folder
2. however, all the updates for the plugins and themes are working without any problems
