- Plesk Onyx 17.5 for Linux
Simultaneous renaming and changing the password of a system user via Domain > example.com > Web Hosting Access fails with the following error:
PLESK_ERROR: Unable to execute usermng: usermng: /usr/sbin/usermod execution failed: usermod: user johndoe is currently used by process 31788 usermng: Unable to modify user: johndoe
Plesk bug #PPPM-7676 which is planned to be fixed on one of the future product updates.
Until a fix became available, change username and password separately.
